Lost in translation: 12 historic city names that vanished from maps

Many well-known cities have not always been called by their modern names. Medieval maps and documents often reflect older forms shaped by language, imperialism, and administrative change. This article presents 12 cities whose historical names differ from the ones used today, reflecting how urban identity can evolve over time.

European merchants from the 1500s onward commonly referred to this major southern Chinese port as Canton, a name that developed from the Portuguese pronunciation of Guangdong, the surrounding province. In contrast, medieval Chinese records and administrative documents consistently used Guangzhou to identify the city itself.

As foreign trade increased in later centuries, Canton remained the dominant term in Western maps and reports. During the 20th century, the Chinese government standardized Guangzhou as the official form, and international publications gradually adopted the modern name in line with updated geographic and linguistic guidelines.

On medieval maps, this Baltic port appears as Reval, a name associated with the surrounding region of Revala and used widely in German and Swedish documents. The local Estonian name Tallinn, often interpreted as meaning "Danish town," existed alongside Reval for many centuries but did not appear frequently in international references. After Estonia gained independence in 1918, the new government adopted Tallinn as the official name for state administration, mapping, and foreign correspondence, gradually phasing out the historical form Reval from everyday use.

In the 17th century, European traders adopted the name Bombay, derived from the earlier Portuguese form Bombaim, which was coined after Portugal arrived in the region. Medieval local settlements, however, used names connected to the goddess Mumbā Devī, and these forms gradually developed into Mumbai in regional languages.

The name Bombay remained common in English during the colonial period and well into the 20th century. In 1995, the Indian government formally adopted Mumbai as part of a broader effort to restore historical and regional place names and align official usage with long-established local terminology.

We now know it as Bratislava, but in medieval German and Central European sources, the capital of Slovakia appeared as Pressburg, a name widely used in administrative records and regional maps. Hungarian documents used Pozsony, while Slovak-speaking communities used earlier forms that later developed into Bratislava.

After the creation of Czechoslovakia in 1918, the new government selected Bratislava as the official name. This decision aligned the city’s identity with the Slovak language and standardized its use in state administration, cartography, and international communication.

English-language maps from the medieval and early modern periods often used the name Leghorn to refer to this port city on the west coast of Tuscany. This form, an anglicized version of the Italian Livorno, appeared in trade documents, port registries, and maritime charts produced in Britain and other Western European countries.

Within Italy, however, the name Livorno remained standard in official records and everyday use. As English cartographic practices modernized in the late 19th and early 20th centuries, Leghorn was progressively replaced in atlases, government publications, and international references, leaving Livorno as the fully standardized name.

In 1930, the Republic of Turkey officially adopted the name Istanbul as part of nationwide language reforms that aimed to standardize geographic names. Yet, during the Middle Ages, European and Byzantine documents consistently used Constantinople, a name introduced in 330 CE when Emperor Constantine refounded the city as the capital of the Eastern Roman Empire.

The form Istanbul existed in local speech for many centuries, especially in Ottoman Turkish administrative and everyday use, but it remained secondary outside the region. It did not replace Constantinople in international publications, maps, and diplomatic records until the early 20th century, when the Turkish government applied the modern spelling in official communications.

Medieval Latin sources refer to this antique city spanning the Rhine River in western Germany as Colonia Agrippina, a designation used in administrative records and church documents. Over time, this Latin name shifted into Cologne in French and later in English.

Within the German-speaking world, however, Köln is the official name employed in government and municipal contexts. Cologne continues to be used internationally in English-language publications, reflecting the city’s long linguistic connection to its earlier Latin and French forms.

During Venetian rule, from the 13th to the 17th century, both the city and, at times, the entire island of Crete were commonly referred to as Candia in European maps, trade documents, and diplomatic correspondence. Local Greek populations, however, continued to use Heraklion (or Iraklio) in everyday speech and regional records. After Crete unified with the Kingdom of Greece in 1913, the Greek government adopted Heraklion as the official name. This change gradually replaced Candia in administrative documents, cartography, and international references.

European travelers adopted the name Peking based on older pronunciations of the city’s name that circulated in foreign accounts during the Yuan dynasty. These forms entered Western languages through early maps, missionary writings, and trade records.

Within China, however, the Ming dynasty formally established Beijing, meaning "Northern Capital", as the administrative name in 1403. The term remained through later dynasties and into the modern period. In the 20th century, the Chinese government standardized Beijing for international use, and over time, it replaced Peking in official English-language publications, atlases, and diplomatic documents.

To refer to the capital of Georgia, European and Russian documents from the medieval period through the 19th century commonly used Tiflis, a form that entered widespread use through administrative records, maps, and travel writing. Yet, the Georgian name Tbilisi existed throughout this time as the local designation.

In 1936, during a series of Soviet administrative and linguistic reforms, authorities formally adopted Tbilisi as the standardized name. After this change, Tiflis was gradually removed from official documents.

Founded as Edo in the medieval period, this ancient city grew from a fortified settlement into a major urban center under the Tokugawa shogunate beginning in the early 1600s. During this time, Edo became the seat of the shogun and developed one of the largest populations in the world.

When the Meiji Restoration transferred imperial authority to Edo in 1868, the new government renamed the city Tokyo, meaning "Eastern Capital." This decision recognized its new status as the national capital and marked the beginning of its role as the administrative and political center of modern Japan.

After a major fire in 1624, the capital of Norway, originally called Oslo, was rebuilt under King Christian IV and renamed Christiania as part of the reconstruction effort. The earlier name continued to appear in local usage and historical references during the following centuries. In 1925, however, the Norwegian government formally reinstated Oslo as the official name, restoring the designation used before the medieval period and aligning administrative records with long-standing local tradition.

Odd words, old meanings

These 10 idioms and phrases are still in use, but don’t always make sense

How much is a notch when it comes to volume? Who is Bob, and why is he everyone’s uncle? What is the difference between a spider web and a cobweb? Languages change with time and use, and English is no exception, but some phrases remain frozen in time, and while we still use them, we don’t always know their literal meaning. Here are 10 idioms and words that don’t make sense, but once did.

We often use the phrase "to a T" (sometimes spelled "to a tee") to indicate something done perfectly, with precision. But is it about the letter "T"? Not really. The original phrase used to be "to a tittle," with tittle being the proper name for the dot of the "i" or the "j," and it conveyed the idea of doing something accurately, down to the smallest detail. Eventually, "tittle" was shortened to "T," but the phrase had already stuck, even if its literal meaning was lost.

Although "fathom" might sound very formal, we all know that it is synonymous with "understand." But did you know that fathom is actually a nautical unit of measurement? From the Old English fæðm ("the span of the arms" or "embrace"), it represented the distance between the left and right fingertips of outstretched arms. Eventually, a "fathom" was standardized to about six feet or two yards, and was mainly used by sailors to measure water depth. It was this connection with depth that led the word to take on a figurative meaning of "getting to the bottom" of something, or understanding it thoroughly.

Popularly, we understand that a "red herring" is something meant to give false clues or distract from another pressing issue. But why a herring? Herrings turn red when smoked and also acquire a strong, pungent smell, which made them a great tool for training hunting dogs, as the smell of the fish covered the trail of the prey. As a metaphor, though, it was popularized in the early 19th century by journalist William Cobbett, who used it to describe how the press was easily swayed by false news.

If something is a "rule of thumb," it means that it’s a common guideline, usually based on experience rather than science. In its origins, this phrase was quite literal: thumbs served as a rule. Tradesmen often used the width and length of their thumbs to take and remember measurements, a system that, though practical and effective, only worked for the owner of the thumb in question. Its use as an idiom comes from 17th century writers comparing this popular method with more scientific measuring systems.

If someone asks us to "take it down a notch," how much should we lower our volume? With "notch," this idiom refers to mechanical dials, like the ones used in a radio, where the notches signal the different levels. And while radios only date back to the 20th century, the roots of this idiom go all the way back to the 17th century and to the phrase "take it down a peg," related to wooden pins used for measurements.

Is there a difference between a cobweb and a spiderweb? Although they are synonymous, most dictionaries will make the distinction that "cobweb" is particularly used for dusty, abandoned spiderwebs. But what does the "cob" part mean? "Cobweb" is derived from the Middle English coppeweb, composed of coppe ("spider") and web ("woven fabric"). If we go one step further, coppe comes from the Old English attorcoppe ("spider"), a mix of attor ("poison") and coppe ("head" or "round thing"). So, despite the slight difference in their actual use, "cobweb" and "spiderweb" mean the same thing.

It isn’t difficult to see how "breaking the ice" might have originated from people actually breaking ice, but what many ignore is that this custom (and the phrase) is rooted in diplomacy and trade. When large trade vessels were unable to advance due to frozen rivers, canals, or harbors, it was common to send people in a small boat to "break the ice" and allow the ship to continue its course. In some places, however, locals would send "icebreakers" to clear the path for a foreign vessel as a welcome and a sign of goodwill. The metaphorical use of the phrase exists in many languages, but it was first recorded in English in the 16th century.

The idea of "letting down your hair" is popularly associated with relaxing and letting formalities aside, but the phrase is rooted in an actual Medieval and Renaissance custom. Traditionally, single women would keep their hair loose and uncovered, but would pin it up once they married. It was not proper for a married woman to be seen in public with their hair down, something they would only do in the comfort of their home, foregoing elaborate hairstyles and uncomfortable pins. Eventually, loose hair lost its social status meaning, but the connection with relaxation remained.

According to historians, no one knows who Uncle Bob is, or what his connection is with simple and easily accomplished tasks, but popular folklore claims to have the answer. According to this theory, the phrase refers to British Prime Minister Robert Gascoyne-Cecil (who went by Bob), appointing his nephew Arthur Balfour as Chief Secretary for Ireland, a position he was woefully unqualified for, but that was made possible because "Bob’s your uncle".

Have you ever wondered why midwives have that name? After all, there is nothing "mid" nor necessarily "wifely" in helping someone give birth. The answer takes us back to Old English, where mid meant "with" or "together with," and wif (the origin of "wife") meant "woman," "female," or "lady," and not necessarily a married female. First recorded around the year 1300, "midwife" was an accompanying person (typically a woman) who assisted mothers during labor. Although the literal meaning of the term is lost to us, the importance of the role was surely the reason this word survived through the centuries.
