Toppeladugård was originally farm of the Häckeberga castle. It was divided as an estate in 1720 by Christina Piper. The current two-storey main building and two wings were built in 1918-1920 by the design of Lars Johan Lehming. Today it is privately owned.

Before 1930 there was another building from the period when the noble family Wrangel owned the Castle.
Carl-Gustaf Wrangel was the owner from 1868 until 1872 and Helmuth Wrangel from 1872 until 1901. Ernst Linder was Rhen married with a daughter Wrangel. Owner between 1901 and 1905.
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.
