Visbia Gothorum. Visby / Gotland.

A fine antique map - bird's-eye view / plan of Visby on Gotland by Braun and Hogenberg, from: Civitates Orbis Terrarum, ... Part 5. Köln, 1596.
TRANSLATION OF CAPTION: In the name of Christian IV. King of Denmark, Norway, the Vandals and the Goths. COMMENTARY BY BRAUN: "On the Island of Gotland, where the Baltic Sea borders Sweden, Livonia and Prussia, in a region extremely well suited for cattle farming, for game, fish, marble quarrying and other vital necessities, lies the splendid city of Visby, famed throughout almost the whole of Christendom, whose large and ancient marble buildings still bear witness to its magnificence today.
In 1288, it was granted its civic rights by King Magnus Ladulas of Sweden and with these the freedom to fortify the town with walls [...]. Right up to the present day, the inhabitants can still show visitors ten churches and four monasteries built in a single style of architecture [...]. It was in Visby harbour that the famous fish was caught, out of whose belly a child was cut, in the year of our Lord 1289."

The view from the west shows Visby from the sea. In the town beyond the harbour, three churches stand out in particular: the Santa Maria Kyrka (Q), the convent church of Sankta Katarina (V) in the centre and on the right the Sankt Petri Kyrka (O). Only Sankta Maria (St Mary's) - the cathedral of the Visby diocese since 1572 - still stands today.
Visby was continuously occupied from the Viking era onwards. In 1161 Henry the Lion granted the city a trading privilege that guaranteed legal security for commercial transactions. Around the middle of the 12th century Visby served as one of the first centres of the Hanseatic League and was called "Regina Maris", Queen of the Sea. In the 13th century, however, the city lost its leading position in Baltic trade to Lübeck.
With the Treaty of Brömsebro in 1645 Visby became part of Sweden. (Taschen)
