Possibly built on the foundations of a Roman castrum fortress, the Moosham castle was first documented in a 1191 deed. It was seized by the Prince-Archbishops of Salzburg about 1285 and from the 14th century onwards served as the residence of an episcopal burgrave. Under the rule of Prince-Archbishop Leonhard von Keutschach from 1495, the castle was rebuilt and extended. In 1520 it became an administrative seat of the Lungau region and was besieged during the German Peasants' War of 1524–25. Archbishop Wolf Dietrich Raitenau stayed here on his flight from Salzburg in October 1611, shortly before he was captured.
Archbishop Count Hieronymus von Colloredo dissolved the Moosham bailiwick in 1790, whereafter the castle decayed. In 1886 the Austrian explorer and patron of the arts Count Johann Nepomuk Wilczek purchased the ruin and had it restored. Up to today the complex is a private property, though its rooms featuring Wilczek's extensive art collection are accessible to the public.References:
Situated in the basement of Metropol Parasol, Antiquarium is a modern, well-presented archaeological museum with sections of ruins visible through glass partitions, and underfoot along walkways.
These Roman and Moorish remains, dating from the first century BC to the 12th century AD, were discovered when the area was being excavated to build a car park in 2003. It was decided to incorporate them into the new Metropol Parasol development, with huge mushroom-shaped shades covering a market, restaurants and concert space.
There are 11 areas of remains: seven houses with mosaic floors, columns and wells; fish salting vats; and various streets. The best is Casa de la Columna (5th century AD), a large house with pillared patio featuring marble pedestals, surrounded by a wonderful mosaic floor – look out for the laurel wreath (used by emperors to symbolise military victory and glory) and diadem (similar meaning, used by athletes), both popular designs in the latter part of the Roman Empire. You can make out where the triclinium (dining room) was, and its smaller, second patio, the Patio de Oceano.
The symbol of the Antiquarium, the kissing birds, can be seen at the centre of a large mosaic which has been reconstructed on the wall of the museum. The other major mosaic is of Medusa, the god with hair of snakes, laid out on the floor. Look out for the elaborate drinking vessel at the corners of the mosaic floor of Casa de Baco (Bacchus’ house, god of wine).
