Clock-tower in Tassin-la-Demi-Lune, Clock tower and heritage site in Tassin-la-Demi-Lune, France.

The monumental clock tower of Tassin-la-Demi-Lune stands on Place Vauboin at the junction of the former Bordeaux and Paris roads. Its Saint-Martin-de-Senozan stone column, hollowed to 60 cm and entered by an iron ladder, rises from a base that once formed a resting bench. A bronze ring marks the start of the octagonal shaft, and four 1.20 m clock faces are decorated with Apollo and owl allegories.

The mayor Étienne Marin launched construction of the clock on Place Vauboin, at the junction of the Bordeaux and Paris roads. The first stone was laid on 23 June 1907 and the tower was inaugurated on 5 April 1908 by the mayor and many public figures. It was paid for by municipal funds and a public subscription, for a total of 16,000 francs.

The clock tower serves as a focal point in the town center where locals pass through daily. It marks where important roads meet and provides a reference point for the community.

The tower stands on Place Vauboin, at the crossing of the former Bordeaux road (RN89) and Paris road (RN7). Its hollow column, 60 cm in diameter, can be climbed from inside using an iron ladder. The base once formed a resting bench, now hidden beneath the floral ornament.

The tower is not a church remnant: it was built as a clock tower, hollowed to a 60 cm diameter so people could climb inside on an iron ladder. Its base originally formed a resting bench, now hidden under floral ornament. The four 1.20 m dials pair Apollo below with an owl above, joined at each corner by a quiver of time's arrows.
