The Tower of Motta Sant'Anastasia was built between 1070 and 1074 by the will of the Count Roger of Hauteville. The massive tower with a rectangular plan, with a base of about 21.5 by 9 by 17 metres, is about 21 metres high and is a typical defensive structure of the early Middle Ages. The roof terrace retains almost intact battlements.
The structure consists of three elevations. Only the first of these is still the original arched windows ogive (external) and at all sixth (inside). The other two square windows, on other levels, such as the current front door, go back to the 15th century.
The ground floor was designed for military housing. In it there are a number of holes for defence.
References:Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
A pleasant 30 minute-walk through the vineyards between Vufflens-le-Château and Denens, offers a stunning view of this magnificent castle, the lake and the Mont-Blanc.
