One of the mightiest former castles in Latvian territory in the 12th-century has been partly reproduced in Tērvete to give a little glimpse of the ancient history of Tērvete and Zemgale, based on archaeological discoveries. The construction of the eastern part of the castle has been completed, and it holds an exposition on Tērvete Castle and Semigallian material culture. It features pictures of Semigallian hillforts, ancient jewellery, clothing, weapons, household items, furniture, as well as a wax sculpture of the Semigallian duke Viestards, and the largest sword exhibition in Latvia.
Every year, on the second weekend of August, the traditional Semigallian festival takes place in the courtyard of the castle, when tournaments of soldiers and knights are held, and an attack on the castle is staged, during which the inhabitants of the castle defend themselves. Meanwhile, the masters of ancient crafts not only trade, but also demonstrate their craft skills, involve festival participants in the activities and invite them to participate in creative workshops for making Semigallian jewellery and household items.
