The Karelia Aviation Museum is located at Lappeenranta Airport. The museum is run by Kaakkois-Suomen ilmailumuseoyhdistys ry. The museum is housed in two covered halls and displays fighter aircraft and smaller objects from the Second World War and onwards.
The first hall, the MG Hall, houses the Mig-21BIS MG-127 fighter. The showcases also feature aircraft instruments and gauges, turbine blades and parts from bombers which saw action during the Second World War. On the walls are flying equipment from the Mig fighter, as well as the wing and fuselage fuel tanks of the aircraft.
The second exhibition hall houses a SAAB 355 Draken fighter and SAAB 91D Safir Trainer. Other exhibits on display in the hall include objects originating from the air battles fought during the ‘Winter War’ and the ‘Continuation War’. During the early part of the ‘Winter War’ (1939-40), on 1st December 1939, Immola airfield was bombed by the enemy’s Tupolev SB-2 planes. It was during this bombing raid that Captain G. Magnusson shot down one of the attacking planes above Lake Rampalanjärvi in Ruokolahti. The plane plunged into the lake, in flames, and its observer was taken prisoner at the perimeter of the airfield. Here, you can examine the wing flap and other parts of this bomber plane.

Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
