Just to the north and completely overshadowed by St Mary's Church, sits the small Royal Chapel, squeezed between two houses. The only Baroque church in old Gdańsk, it was built between 1678 and 1681 to fulfil the last will of the primate of Poland of the time, Andrzej Olszowski. It was designed by famous royal architect Tylman van Gameren. Its façade is its more attractive feature, and bears the coats of arms of Poland, Lithuania and King Jan III Sobieski (the founder of the chapel).

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.
