Hamburg Town Hall was built from 1886 to 1897 and with its impressive architecture dominates the centre of the city. The magnificent sandstone building houses the city's senate and parliament.
On the outside the architectural style is neo-renaissance, which is abandoned inside for several historical elements. It is one of the few completely preserved buildings of historicism in Hamburg. Built in a period of wealth and prosperity, in which the Kingdom of Prussia and its confederates defeated France in the Franco-German War and the German Empire was formed, the look of the new Hamburg Rathaus was intended to express this wealth and also the independence of the State of Hamburg and Hamburg's republican traditions.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
