Built between 1402 and 1404, Tallinn's Gothic Town Hall building is the only Gothic town hall building in northern Europe that remains intact, sitting as the centerpiece of Tallinn's main square. The structure was originally a meeting place for rulers, though today it is mostly used for hosting visiting presidents or kings, as well as for concerts. The impressive interior features colorful meeting halls, vaulted ceilings, intricate wood carvings and some of the city's most prized artwork, including the famous Tristan and Isolde carved bench. At the top of the Town Hall's spire sits a weather vane called Old Thomas, which is a symbol of the city and has been there since 1530.
Town Hall Square is filled with outdoor cafes and hosts open-air concerts and festivals, such as the summer medieval Old Town Days celebration. In July and August, Tallinn Town Hall opens up to visitors as a museum with exhibitions in the cellars. From late June through August, visitors can climb the 64-meter (210-foot) tower for gorgeous views of the city. In the winter, this is where you'll find the Christmas markets.
Tallinn Town Hall is located at Raekoja plats 1. From June 25 to August 31, the museum and tower are open Monday through Saturday from 10am to 4pm. Tickets cost 4 euros.
