A one-bedroom apartment inside Hector Guimard’s Castel Béranger—the architect best known for Paris’s iconic Art Nouveau Métro entrances—pairs original period details with a design-led renovation by its owner.

The château dates to the 16th century and was once held by one of France’s oldest noble families, while the wider estate carries a permit for 17 villas within its forested grounds.

Restored and expanded over nearly 30 years, the property includes 7-stall equestrian facilities, a resort-style pool, tennis court, greenhouse, maintained gardens, and a network of trails.

Number 6 forms part of the city’s famous Royal Crescent, built between 1767 and 1774 by John Wood the Younger. Comprising 30 townhouses behind a single curved facade, the crescent remains one of the most recognizable architectural landmarks of Bath and an icon of Georgian urban design.

Five minutes from Gordes, this 19th-century stone farmhouse combines the architecture of a rural Luberon property with a mature garden attributed to Michel Semini, a Provençal landscape designer known for private gardens in the South of France, among them the garden at Yves Saint Laurent co-founder Pierre Bergé’s Saint-Rémy-de-Provence estate.

A working Irish village fell into ruin. A Ryanair co-founder spent a fortune bringing it back. It became a five-star hotel. Now the whole village is on the market for €20 million.
