It is situated on Gamlebyviken lake and was built in 1829 in the so-called neoclassical Tjust empire style, after the original 17th-century mansion was destroyed by fire.
During the Middle Ages, the site of the present mansion was close to a village named Mæm (as spelled in 1379).
In the early 17th century Mem was owned by Sidonia Grip (1585-1652) who on October 6, 1616, married her cousin Count Johan Casimir Lewenhaupt (1583-1634).
In 1809, the seventeenth century mansion was destroyed by fire; twenty years later, in 1829, its owners, Count Gustaf Lewenhaupt and his wife Sophie, commissioned architect Uppman and builder Jonas Jonsson to rebuild the house in the then fashionable neoclassical Empire style.
It contains informal, low-ceilinged family living accommodation on the ground floor, and a high-ceilinged piano nobile above.
