Square Jan-Doornik, Urban park in the 16th arrondissement of Paris, France

Square Jan-Doornik is a garden in the 16th arrondissement of Paris, laid out in 1989 on the 1986-1987 cover of the old Auteuil line trench. A straight paved walkway runs between a low green wire fence and a row of black benches and lantern-topped lampposts, with a light stone wall and plaque on the right. Plantings include flower baskets, grasses and ferns, banana trees, a walk of flowering pear trees, a pergola of climbing roses and clematis-covered trellises, plus a children's playground and a book box.

The walkway covers the trench of the former Auteuil line, opened in 1854 and closed in 1985; from 1900 it carried four tracks along the middle of boulevard Flandrin. The trench was covered in 1986-1987, and the promenade was laid out in 1989 above the RER C tunnel between the Henri-Martin and Avenue-Foch stations. The square is named after Jan Doornik (1905-1941), a Dutch resistance fighter.

The square is mostly used by families and local residents who come for short walks or to let children play in the designated area. A pergola covered with climbing roses and trellises with clematis give the space a character that feels different from the larger parks nearby.

The park is close to the Porte Dauphine station on metro line 2 and the RER C stop at avenue Henri-Martin, making it easy to reach. The paths inside are mostly flat, and the entrance on boulevard Flandrin is easy to spot thanks to the climbing roses framing the gate.

The walkway hides the covered trench of the former Auteuil line, opened in 1854 and closed in 1985; the cover was built in 1986-1987 and the promenade laid out in 1989. The entrance sign on boulevard Flandrin records this. The square also holds a book box and a play area for children.
