Tolquhon Castle was built by William Forbes, 7th Laird of Tolquhon, between 1584 and 1589 as an extension to the earlier tower house known as Preston's Tower. Although ruined, the castle has been described as the most characteristic château of the Scots Renaissance. It is in the care of Historic Scotland and is open to the public.
After William Forbes' death his descendants continued to occupy Tolquhon until 1718, when they were forced to move out due to debts incurred by the failure of the Darien scheme. The castle subsequently decayed and is now a ruin.
The main entrance is on the north range of the castle, with the Preston Tower forming the north-east corner. The gallery occupies the first floor of the west range, while the main hall is in the south range, accessed via a stair from the courtyard. A prison was located within the south-east tower. To the north of the main quadrangle is the walled outer courtyard, with the remains of a doocot.References:
The eight towns in south-eastern Sicily, including Ragusa, were all rebuilt after 1693 on or beside towns existing at the time of the earthquake which took place in that year. They represent a considerable collective undertaking, successfully carried out at a high level of architectural and artistic achievement. Keeping within the late Baroque style of the day, they also depict distinctive innovations in town planning and urban building. Together with seven other cities in the Val di Noto, it is part of a UNESCO World Heritage Site.
In 1693 Ragusa was devastated by a huge earthquake, which killed some 5,000 inhabitants. Following this catastrophe the city was largely rebuilt, and many Baroque buildings from this time remain in the city. Most of the population moved to a new settlement in the former district of Patro, calling this new municipality 'Ragusa Superiore' (Upper Ragusa) and the ancient city 'Ragusa Inferiore' (Lower Ragusa). The two cities remained separated until 1926, when they were fused together to become a provincial capital in 1927.
