Porth-y-Tŵr (Welsh for Tower Gate) is a gatehouse and bell tower overlooking St Davids Cathedral. It is the sole survivor of four medieval gates to the walled Cathedral Close. The 13th-century octagonal tower, adjoining the gateway, now contains the cathedral's bells.
What is nowadays the bell tower was used by the bishops of St Davids for their consistory court and a record office for the episcopal see. The south tower and the range of rooms above the gate were used as a council chamber. Well appointed apartments, suitable for the mayor, were accessed via a doorway on the town side of the tower.

The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
