Duivenvoorde Castle was first mentioned in 1226, making it one of the oldest castles in South Holland. The castle is remarkable in that it has never been sold, which can be said of very few Dutch castles. It has passed by inheritance through several noble houses, sometimes through the matrilineal line. For the first five centuries of its history, the castle was owned by one family, the van Duivenvoordes, who gave their name to it. Although thus named, the van Duvenvoirdes properly formed part of the House of Wassenaer, an ancient noble family which has played an important role in Dutch history. Towards the end of the 17th century an owner of Duivenvoorde Castle, Johan van Duvenvoirde, readopted the name of van Wassenaer. Therefore, although the same family remained in the House, this was under a different name.
The last private owner of the castle was Jonkvrouwe Ludolphine Henriette, Baroness Schimmelpenninck van der Oye (1891-1965). Knowing that with her death the house would be sold and the furniture dispersed, including the collections of portraits, porcelain and clothing and textiles, she decided to close the house and leave it in the care of a foundation for restoration. The stated aim was to restore the castle to its appearance in 1717, although in practice this has not always been possible. The terrace constructed around 1844 has been kept, and the opening of previously sealed windows to allow more light into the living room has taken away some symmetry. The interior has been redecorated to match the colours of 1717, and later piecemeal work on the ceilings has been left in place. Today Duivenvoorde is a musem.
In 1717, two Roman stones were installed as plaques in the front hall. The larger of the two stones, dated between 196 and 198 AD, has an inscription on the front about the repair of an armory by Roman troops; the text on the other side is older, dating from somewhere between 103 and 111 AD. In the making of the newer text, the stone was made smaller, damaging the older text. The smaller stone has a text which, through knowledge of the people named there in, can date the stone to around 205 AD.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.
