The Red Tower (which is actually white) is the only defence tower left from medieval Hanseatic city of New-Pärnu. It is the oldest city’s architectural monument and was used as the prison. According to the chronics, in 14th century Pärnu was encircled by a fortified wall with many towers: the round Viliand Tower, also know as the White Tower, in the north-eastern corner and Red Tower in the south-eastern corner. There may have been also the Holy Spirit’s Tower. After a well-needed reconstruction in 1893 it acquired its current look.
The tower got it's name by the red lining covering both its inside and outside. In 1624, the tower had four floors and a six meter deep prison floor. Three floors been preserved. Red Tower was restored in 1973-1980 without it's original brick lining.
Louisenlund is a site with one of Denmark's largest collection of megaliths. Some 50 stones standing upright among the trees, many of them over 2.5 metres high. The megaliths, which bear no inscription, stand on low mounds or over graves where the remains of burnt bones are buried. In the early Bronze Age and late Iron Age (1100 BC), it appears to have been common practice to set megaliths over graves of this kind. The stones stand alone or in small groups. As the site has not been archeologically investigated, it is not known why the stones were raised there. Another important megalithic site on Bornholm is Gryet, a small wooded area 5 kilometres west of Nexø. Originally it had more than 60 megaliths. Some have now been removed while half those remaining have fallen to the ground. The highest of them, once standing on the mound towards the south of the wood, was removed in the 17th century to be used as a gravestone. Louisenlund was bought by King Frederik VII when he visited Bornholm in 1851. He named it after his mistress, Countess Louise Danner.
