Šventoji is an important archaeological site as the first artifacts are dated about 3000 BC. A famous cane shaped as moose head was also found in the town. It is a former fishermen village now turned into a tourist town. The town always struggled to develop a port, which had to compete with nearby Klaipėda and Liepāja. Larger port was constructed in the second half of the 17th century, especially when in 1679 it was leased to English merchants. It was destroyed in 1701 during the Great Northern War. During the times of the Russian Empire (1795–1915) the port was moribund and began developing again only when it became part of Lithuania in 1921. Two piers were constructed, but they were frequently covered in sand. Thus it never grew into a bigger port.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
