Näsby estate belonged to Uppsala archbishop in 1300s and in 1520s it was donated to Kristina Nilsdotter (Gyllenstierna). In 1571 it was acquired by Gustav Axelsson Baner. Originally built in the 1660s and designed by Nicodemus Tessin the Elder, the current Näsby Castle is located in the picturesque and natural setting of Näsbyviken. The castle was burned to the ground in 1897, but was rebuilt according to the original design on the initiative of Carl Robert Lamm and Dora Lamm who moved into the castle in 1905. Parts of the old castle garden still exist and are well preserved. Today Näsby is a conference center with a hotel and restaurant.
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.
