Orangery Park of the Klinglin Castle

Built in 1735 by François-Joseph de Klinglin, Royal Lender of the province of Alsace, this remarkable Regency-style building is the last remaining witness of the castle he had constructed, which was destroyed during the Revolution. The architect Jean-Pierre Pflug, also responsible for the Strasbourg prefect's hotel, is believed to have designed the plans. The building is distinguished by its raised ground floor, adorned with a full balcony-gallery facade accessible by a double staircase, and an attic floor. It is flanked by two symmetrical square pavilions.

Around this residence, Klinglin created a vast park, enhanced with fountains and about forty statues inspired by Greek mythology. The park gates, staircase, and balcony, made by Sigismond Falkenhauer, are now classified as Historic Monuments.

The Orangery, which now houses the college offices, has been redesigned in a contemporary style evoking the gardens of old, described in an 18th-century text as "a mass of flowers and orange trees." The two pink sandstone sphinxes, now placed on either side of the entrance to the Joséphine Pavilion of the Orangery in Strasbourg, were originally part of the decorative elements of this park.
