Hazmburk (Hasenburg) is a Gothic castle ruin located on a mountain peak near the town of Libochovice. The castle was home to Zajíc noble family of which Zbyněk Zajíc was the first to own the castle (since 1335). After 1586, it remains desolate and later, in the period of romanticism, it became a source of inspiration for writers, most notably K.H. Mácha. The castle is open to public in summer and can be either accessed from the nearby village of Klapý or from the train stop Slatina pod Hazmburkem.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.
