The Pommern, formerly the Mneme (1903–1908), is a four-masted barque that was built in 1903 in Glasgow at J. Reid & Co shipyard. It was one of the Flying P-Liners, the famous sailing ships of the German shipping company F. Laeisz. Later she was acquired Gustaf Erikson of the Finnish Åland archipelago, who used the ship to carry grain from the Spencer Gulf area in Australia to harbours in England or Ireland until the start of World War II. After World War Two, she was donated to the town of Mariehamn as a museum ship.
Today Pommern is part of the Åland Maritime Museum representing the history of ship and seafaring in Åland. The Maritime Museum is considered as one of the world’s finest museums related to merchant sailing ships.
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.
