Nestled between Notre‑Dame‑de‑Lorette church and Montmartre, Square Alex‑Biscarre is a charming circular park of 1,180 m², created in 1964 on the former garden of the Hôtel Dosne‑Thiers. It’s named after Alex Biscarre (1891‑1977), a long-serving Paris councilor.

Émile Dosne acquired the townhouse in 1832. Adolphe Thiers, the first President of the Third Republic, penned parts of his History of the Consulate and the Empire there. The building was destroyed during the Commune, then rebuilt between 1873–1875, and given to the Institut de France in 1905, which subsequently granted the garden to the City of Paris.

Today, the park is a peaceful oasis, with Austrian black pines, a copper beech, maples, magnolias, and horse chestnuts offering a lush canopy. Local families frequent the well-equipped playground, though it sometimes closes for upgrades (next scheduled closure: May 19 to July 18, 2025).

The gently sloping grounds provide shaded seating under a slate-roofed pavilion. Amenities include a book-sharing box, drinking water fountain, and restrooms. No wifi, vending machines, or pets allowed.

Ideal for families, locals, or anyone seeking tranquility, the square also offers architectural interest, bordered by elegant Nouvelle‑Athènes facades and the historic Hôtel Dosne‑Thiers, now a library.

It’s perfect for a stroll, reading, picnic or quiet break—visit in under an hour. Access via Metro line 12 (Saint‑Georges).

Visitor info: Open 9 AM–7 PM (May–August, holidays included), free entry, no pets.
