Smailholm Tower was originally built in the 15th century or early 16th century by the Pringle family. It was designed, in common with all Scottish peel towers, to provide its occupants with protection from sporadic English raids. The tower was attacked by English soldiers in 1543, 1544 and again in 1546, when the garrison of Wark Castle sacked the tower and carried off prisoners and cattle. The castle was successfully defended against the English in 1640, by Sir Andrew Ker of Greenhead.
Smailholm was obtained by the Scotts of Harden around this time. The Scotts – ancestors of Sir Walter – rebuilt parts of the tower and barmkin. In the 18th century the tower decayed, following the family's move into nearby Sandyknowe. The last owner, the Earl of Ellesmere, handed the property into state care in 1950. It was restored in the 1980s, and now operates as a museum.
Smailholm was a relatively small tower house, offering around 200 m2 of floorspace, later extended by construction of a hall house and second kitchen within the barmkin, or courtyard. The rectangular tower is of four storeys, situated on top of a rocky outcrop.
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.
