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.

What is the name for the tip of your shoelaces?

While we typically go about life describing the end of our shoelaces as ‘the end of the shoelace’ or the whites of the egg as ‘egg whites’, these things, and many more, have names of their own, even if they are not always widely known or used. Let’s have a look at 11 common things that have proper names, even if no one uses them.

The little plastic or metal tip at the end of shoelaces or drawstrings is there to prevent the fibres from fraying, and to make it easier to pass the lace or drawstring through a hole. Its proper name is ‘aglet’, from the French aguillette, meaning ‘needle’, a reference to its use in helping to thread the string through the hole.

Erasers at the end of wooden pencils are not usually glued together, but they are instead held together by a little metal band. This band is called a ‘ferrule’—from Medieval Latin viriola or ‘little bracelet’—and the term can be used for any metal band that strengthens or fastens a joint, such as those used in handles, to hold brush bristles, or to secure a connection between two cables.

The ‘little plastic table on the pizza’ is quite a long name for something aptly named ‘pizza saver’, but no one seems to really care. It was invented in 1974 by an Argentine pizza maker, who named it SEPI or separador de pizza (‘pizza separator’). In America, it was patented as a ‘package saver’ in 1985, though it was later renamed ‘pizza saver’.

Most mathematical symbols have proper names that are not regularly used, and the division sign is no exception. It was officially introduced into mathematics as a symbol of division in 1659 by the Swiss mathematician Johann Rahn in his influential work Teutsche Algebra. This sign is called an ‘obelus’, from the Greek obelos, meaning ‘sharpened stick’ or ‘skewer’, as it was initially used as a pointer for questionable passages in a text.

Paper cups and their corresponding cardboard sleeves to protect our hands from the heat or the cold are relatively new, but their proper names are not—at least, the name for the cardboard sleeve. This holder is called a ‘zarf’, an Arabic (zuruuf) and Turkish (zarflar) word used for ornamented cup holders, usually made from metal. The materials and the details of the zarf have changed, but the purpose still remains.

Do we need a more technical term than ‘armhole’ for a hole meant for an arm to go through? Maybe not, but the technical term still exists. An ‘armscye’ (pronounced arm-sigh) is the proper term used in sewing and patterns to describe the opening on a garment where the sleeve is attached. The word is a compound of ‘arm’ + scye, a Scots word meaning ‘opening’. So, in the end, ‘armscye’ just means ‘armhole’.

We often use the words ‘railing’ or ‘handrail’ when talking about a staircase, but these terms only describe the top portion of it, not the pillars that support the handrail. The pillars and the rail altogether are called a ‘banister’, a corruption of the word baluster, derived from the Italian balaustro. The term originally was used for the pillars, but eventually came to mean the entire structure.

Not all beverage foams are equal. The foam on top of alcoholic beverages, in particular, is called ‘barm’, a term derived from Old English beorma, meaning ‘yeast’ or ‘leaven’, and it's mainly used for the effervescence of fermented liquors such as beer, ale, or wine.

Did you know that the white (or clear) part of the egg is called the ‘albumen’? The term entered English as a loan from Latin, where _albumen_—from albus, ‘white’—was used in the same way. Though it is not widely used in everyday life, it’s still the correct term for that part of the egg.

As a rule of thumb, you should always assume that all marks, symbols, and strokes in calligraphy have a proper name, even if it's not often used. When it comes to the lowercase letters ‘j’ and ‘i ’, the little dot on top is not a dot, but a ‘tittle’. This name comes from the Latin _titulus_—meaning ‘title’, ‘inscription’, or ‘small mark’—and was initially used by scribes to distinguish these letters in their cramped writing.

If you ever got lost in the mall or the museum, you must have come across a map that marked your location using an arrow or a pointer, usually accompanied by the phrase ‘you are here’. Well, that pointer is called an ‘ideolocator’, a combination of the Greek idea, a ‘mental image, concept, or visual representation’ (in this case, the pointer), and the Latin locatus, meaning ‘to place’ (the specific location on the map). For the sake of convenience, we will keep calling it the ‘you are here’ sign.
