The oldest part of the Castle Complex in Szamotuły is a Gothic Halszka's Tower (Baszta Halszki) from the XV century. At the beginning, it had a typically defensive function, and in the 16th century it was readapted into living quarters. Halszka, the princess of Ostróg, who was also called Black Princess, was living there for 14 years. Ages ago, the high tower was integrated with defensive walls and defended the access to the caste gate. Currently, there is an exhibition of the museum on the four storeys of this very well preserved lofty building. It presents the history of Szamotuły and its surroundings from the times which are known only from the excavations until 1945.The main building of the castle is only slightly younger than the tower. Originally, it was built in the Gothic style and then rebuilt in the spirit of the Renaissance period. It was being modernized and was gradually losing its original defensive character in the next centuries. The last renovation from the second half of the 20th century restored a little the Gothic form of the monument. Today, the fittings of a noble residence are presented in its interiors. Authentic furniture from distant periods, rich fabric, carpets, Chinese and West-European porcelain as well as other monuments can be seen there. In the entrance hall there is a genealogical tree of Szamotulski and Górka family and a foundation plaque from 1518.The Orthodox art is the speciality of the permanent exhibition in Szamotuły. About 490 items connected with it, including 200 icons, were collected here. Apart from this, the museum has nearly 11.000 valuable objects of different kind. The castle also serves as a cultural centre. Different temporary exhibitions and other events like concerts, lectures or popular poetry meetings are organised here. A small Inn "Sanguszko", which offers three double rooms as well as a bar and restaurant, is situated next to the museum.
