Sundrum Castle is located 1.5 kilometres north of Coylton. It was originally built in the 14th century for Sir Duncan Wallace, Sheriff of Ayr, and considered one of the oldest inhabited castles in Scotland. Long-term owners included the Cathcart family, and the Hamilton family, who expanded it the 1790s, incorporating the original keep into a mansion.
It was further expanded in the early 20th century by Earnest Coats. For a time it was then a hotel, though fell into disrepair. After extensive renovations in the 1990s, it was split into multiple privately owned properties. The Sundrum estate now also includes a holiday park.
The castle is split into three separate properties, consisting of the original tower keep, and separate Georgian and Victorian wings, each with their own style.
References:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
