Steninge Palace, Baroque palace in Märsta, Sweden

Steninge Palace is a Baroque palace built 1694–1698 to designs by Nicodemus Tessin the Younger, overlooking Lake Mälaren near Märsta. The main building stands on a high terrace with a wide staircase and balustrade, flanked by two small square wings; below, plantings run down to the lake, with two pairs of wooden wings on either side and a large park behind, laid out with Johan Hårleman's involvement.

Carl Gyllenstierna commissioned architect Nicodemus Tessin the Younger to design the palace following French Baroque principles, completed in 1705. The construction reflected European trends and influenced how similar estates would be built in Sweden.

The palace's name comes from Steninge, the estate recorded as early as 1299 with its first known owner, Lady Katarina. Carl Gyllenstierna gave the completed palace to his bride Anna Soop as a wedding gift in 1706. In the park stands a Gothic-style monument to Axel von Fersen the Younger, erected in 1813.

The grounds are accessible for walking and exploration, so comfortable shoes are recommended for navigating the paths. The estate can be visited throughout the year, with seasonal changes affecting how the gardens and landscape appear.

The stone barn west of the palace was built in 1873 for Baron Oscar von Otter to designs by architect Carl Sandahl. Since 1999 it has housed Steninge Slottsgalleria, with shops, a garden centre and a café-restaurant. It was declared a listed building in 1979.
