The Estienne‑d'Orves Square, established in 1867 by Jean‑Charles Alphand during the Second Empire, offers a green and serene retreat at the foot of the Sainte‑Trinité Church. The garden is carefully arranged around the symbolic number three – echoing the church’s three-door façade – featuring three distinct green areas connected by winding pathways that lead to a triple-basin fountain crowned by statues representing Faith, Charity, and Hope, created by Duret and Lequesne. This symbolic layout is complemented by a grand staircase linking the square to the upper level.

The site’s history adds depth and character: it was built on the former hamlet of Porcherons during Haussmann’s urban renovation, replacing guinguettes once frequented by soldiers and Parisians seeking conviviality. Renamed in 1944 in honor of Honoré d’Estienne d'Orves, a French Resistance hero, the square pays tribute to his bravery.

The square is home to about thirty trees, including a spectacular 26 m Caucasian wingnut (pterocarya) planted in 1862, along with camellias, magnolias, hydrangeas, and alders, providing shade and delicate fragrances. The overall atmosphere is one of a cool, leafy oasis, perfect for reading, picnicking, or enjoying a peaceful urban respite. You’ll encounter families, local workers, tourists, and students alike.

Children enjoy the playground, while benches surrounding the lawns offer panoramic views of the church and a peaceful rest spot in a bustling area. Some visitors note the lack of arched benches that would provide more comfort.

The city has designated the garden as an Ecojardin and Accessibility‑Enhanced Neighborhood, ensuring ecological upkeep and accessible facilities. Despite being near busy streets, the green setting and architectural surroundings create a pleasant escape, though traffic noise may occasionally be heard.

Practical info: The square is free and open daily from 8 AM to 9:30 PM in summer and until 7:30 PM in winter, depending on the season. It offers drinking fountains, potable water, and public Wi‑Fi. Public toilets are nearby at 21 rue d’Amsterdam. The landscaped environment and facilities make it ideal for families or anyone seeking a restful pause after visiting the church or the nearby Opéra district.
