The castle is located in the town of Fénis in the Aosta Valley region, at about 13 km from the city of Aosta.
The keep has a pentagonal layout, with towers at the corners.
It is surrounded by a double boundary wall with battlements and by a series of watchtowers linked by a walkway.

Despite its impressive defensive structure, the castle is situated at the top of a small knoll and not of a promontory or another inaccessible and easily defensible place.
In fact it was not built for military purposes, but to serve as a prestigious residence for the Challant family.

The inner courtyard, at the centre of the keep, shows a semi-circular stone staircase and wood balconies.
At the top of the staircase a 15th-century fresco features Saint George killing the dragon, while the walls of the balconies are decorated with images of sages and prophets and proverbs in old French.
The frescoes are attributed to a painter from the school of Jaquerio.

The interior of the castle is divided into three floors: on the ground floor it is possible to visit the weaponry, the kitchen, the woodshed and the storage tank to collect rainwater.
On the first floor there were the rooms of the lords of the castle, the chapel with frescoes by Giacomo Jaquerio and his school and the court.
The second floor, in the attic, was dedicated to the servant's quarter and is not visitable.
