The Jelgava Castle stands between the Lielupe and Driksa rivers. The Baroque castle was designed by the well known Italian architect Francesco Bartolomeo Rastrelli, and this was the most important piece of early work that he did. The Latvian Agriculture University is housed in the castle today. A museum was established in 1968. +371-6300-5617. The socle story of the south-eastern wing has the graves of rulers from the Duchy of Courland – members of the Kettler and Byron dynasties, which ruled from 1569 to 1791. There are 18 restored sarcophagi here.
