The renowned Florian Gate, built around 1300, is the only one of the city's original eight gates that was not taken down during the 19th-century modernisation. It is enhanced with a later addition at the top, and the walls attached to it, along with the two towers, have been preserved. It is part of a museum called the City Defence Walls and one admission ticket can be used to gain entrance to both the Florian Gate and the Barbican.
