Tērvete village is famous for the historic hillfort built for the kings of Western Zemgale in the Middle Ages. According to popular legend the Semigallian king Namejs made a ring called the 'namejs' so he could be identified by his family. But his enemies got hold of this information and sought the ring to kill the king (during a war) to have victories. The villagers also created these rings in order to protect the King. And for this reason Namejs is a popular ring for Latvians. In 1287 the Semigallian castle was destroyed by the Livonian Order of knights. In 1335 the wooden castle Hof zum Berg Kalnamuiža was built by the Order of Livonia near to the site of the former Semigallian fortifications, destroyed by the Lithuanian forces in 1445.
A second legend describes the story of the German crusaders slowly moving into Latvian territory in the Middle Ages, taking over tribe after tribe. Namejs, the Semigallian king, was the last to subdue to the crusaders' power. Namejs and his people left their land and went south into Lithuanian territory. Namejs didn't want his people to forget their heritage and their origins and had the namejs ring designed for all of his people so that they could identify each other and have a common bond. Now it is a popular ring amongs Latvians that live outside of Latvia because it shows their love for Latvia and recognition of their heritage.
In 1819 K.F.Watson declared the hillfort on right bank of Tērvete river to be the site of the legendary Tērvete castle described in chronicles from the Middle Ages The hillfort was excavated by August Bielenstein between 1866 and 1892 The expedition of the Latvian Museum of History led by E. Brīvkalne carried out excavations in 1952-53 and 1954–59.References:
The Palace of the Grand Dukes of Lithuania was built originally in the 15th century for the rulers of the Grand Duchy of Lithuania. The Royal Palace in the Lower Castle evolved over the years and prospered during the 16th and mid-17th centuries. For four centuries the palace was the political, administrative and cultural center of the Grand Duchy of Lithuania.
Soon after the Grand Duchy of Lithuania was incorporated into Tsarist Russia, Tsarist officials ordered the demolition of the remaining sections of the Royal Palace. The Palace was almost completely demolished in 1801, the bricks and stones were sold, and the site was bowered. Only a small portion of the walls up to the second floor survived, that were sold to a Jewish merchant Abraham Schlossberg around 1800 who incorporated them into his residential house. After the 1831 uprising, the czarist government expelled Schlossberg and took over the building as it was building a fortress beside it. Before the Second World War it was the office of the Lithuanian Army, during the World War II it was the office of the German Army, and after World War II it was used by Soviet security structures and later transformed into the Palace of Pioneers. Fragments of Schlossberg's house have become part of the Eastern Wing of the restored Royal Palace.
A new palace has been under construction since 2002 on the site of the original building. The Royal Palace was officially opened during the celebration of the millennium of the name of Lithuania in 2009.
