Tour Haldimand, Neo-Gothic tower in Lausanne, Switzerland

Tour Haldimand is a circular Neo-Gothic ruin about 5 metres in diameter, with a base of rough fieldstone, a pointed-arch doorway and two upper storeys faced in dressed sandstone. It stands at the end of Quai d'Ouchy between Denantou Park and Lake Geneva, surrounded by an asphalt road and parking spaces.

The tower was built around 1830 near the Vuachère river mouth and relocated to its present site in 1901 to make way for Ouchy quay development. This move was part of major urban reshaping in Lausanne's growth.

The tower is named after William Haldimand (1784–1862), an English banker who bought the Le Denantou estate near Lausanne in 1818 and built the tower on a spit of his park by Lake Geneva. It was one of three artificial ruin towers erected by wealthy friends in a private architecture contest, and Haldimand's entry won.

The tower sits within Denantou Park and is easily reached on foot through various pathways. Multiple viewpoints in the park allow you to survey the lake and surrounding hills from different angles.

Between 1999 and 2001, the tower underwent major restoration work that added a concrete crown to its roof. This modern addition merges the historic structure with contemporary repair techniques and is clearly visible from above.
