Hôtel de Thévalle, Private mansion in Angers, France.

The Hôtel de Thévalle is a private mansion in Angers, built in the 15th–16th centuries to designs by architect Jean Delespine. Its tall stone facade shows squared blocks of mottled beige and grey, a carved frieze above the lower floor, and a steep slate roof with dormer windows and a small sculpted pediment. A gabled wing angles back on the left, and a black wrought-iron balcony projects from one lower window.

The building was constructed in the 15th century and underwent major renovations in 1561 by architect Jean Delespine, who added Renaissance elements. This transformation reflects the shift from medieval to more modern architectural styles.

The mansion's name comes from the Thévalle family, and its 1561 Renaissance reworking by architect Jean Delespine is the detail to look for: carved stonework above the lower floor and a sculpted pediment crowning the slate roof. The ground floor now houses a travel agency whose sign, "Chango Voyages", sits in the wide arched opening.

The building is protected as a historical monument and is located on Rue Toussaint in Angers where it remains a preserved structure. Visitors should be aware that this is a private residence, so access may be limited.

The mansion contains four separate staircases connecting different sections and features underground chambers demonstrating medieval construction methods. These hidden spaces reveal advanced building techniques from an earlier era.
