St. Michael Archangel church is the oldest building in Gdynia. Originally built by nuns of the Norbertine Order, it replaced a pagan temple in 1224. The church was reduced to a pile of rubble during the war with Sweden in 17th century. After its restoration it served the Catholics until the last days of World War II when the tower was hit by a Soviet cannon ball, fired for fun. Yet again did the Kashubians have to rebuild their temple. It towers the Kępa Oksywska up to over 40 m above the water table, surrounded by a cemetery. Very many honourable people from Gdynia and Pomerania rest there; it also makes a Pantheon of the Navy: the walls of this historic church are lined with commemorating plates honouring the II World War Polish warships, graves of the outstanding navy commanders and the September 1939 defenders of the Polish Coast, holders of the Virtuti Militari crosses.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.
