Town Hall tower was built at the same time as the building itself, between 1402 and 1404. In 1530, a weather vane was placed at the top of the tower which the people named 'Old Thomas'. He remains one of Tallinn's most popular symbols and is considered to be the city's guard and defender. The original Old Thomas (from 1530) is stored in the ancient cellar of the town hall.
In summer, visitors to the city can climb the winding staircase up the octagonal tower and enjoy the stunning views over the Old Town and surrounding areas. In order to reach the clock balcony of the tower that is 34 m above the ground, you need to climb 115 stairs. The higher you get, the steeper and higher the stairs become.
