Château de Chassay, Renaissance castle in Sainte-Luce-sur-Loire, France.

Château de Chassay is a Renaissance-style manor in Sainte-Luce-sur-Loire that houses the town hall. Its pale pink facade, divided by vertical bands of lighter stone, rises to a taller central section with a steep four-sided roof, an arched doorway, a balcony with a rounded window and a small round window near the top; a conical turret stands on the left and two brick-coloured chimneys rise from the grey slate roof.

A document from 1096 records the castle at Chasseil, an early name for Chassay, as a possession of the Bishops of Nantes. In the mid-15th century Bishop Amauri d'Acigné had it surrounded by moats, but Duke François II of Brittany seized it and turned it into a hunting lodge, returning it to the bishopric only in 1500. Henri IV and his retinue stayed there on 13 April 1598. In 1683 Bishop Gilles de Beauvau's declarations distinguished the 'Petit château', the present building, from the 'Grand manoir' to its north, which was later abandoned and demolished in the 20th century. Sold as national property on 27 January 1791 to the Nantes shipowner Dubois-Violette for 109,000 livres, it was bought in 1827 by the comtesse de Bondy, sold in 1956 to an agricultural cooperative, and acquired by the commune in 1974 for use as the town hall.

The name Chassay derives from Chasseil, as the estate was called in a 1096 document. Since 1974 the building has housed the mairie of Sainte-Luce-sur-Loire; until 2007 its grounds served as an open-air screen showing the pyrotechnic tales of the company Féerie during summer fireworks.

The château has housed the town hall of Sainte-Luce-sur-Loire since 1974, and in 1989 new buildings were added to the east to hold the municipal services. Visitors can walk past the low stone wall and see the façades, the slate roofs and the two brick-coloured chimneys from outside; the interior is given over to administrative offices.

The 11 June 2024 listing covers more than the main building: it also protects the rotunda topped by a cupola, the platform flanked by its two north-west and south-west turrets, the shell fountain there, the water feature with its fixed bridge, the terrace walls, the moats and the towers. Until 2007 the château served as a giant screen for the Féerie company's pyrotechnic tales during summer fireworks.
