This charming monument was built in the 18th century on the site of a previously destroyed manor house.
In the second half of the 18th century, the estate was purchased by Jan Joachim Deptowski, who built a new small manor house on the property. Redeemed by Count Sierakowski, the manor house took on a classicist form, unchanged to this day. The count was one of the most distinguished citizens of Pomerania, he was a participant of the Great Sejm and a senator of the Kingdom of Poland.

After World War II, the monument was used for apartments, and since 1974 it has been the seat of the Society of Friends of Sopot, which offers a rich cultural program: literary evenings, concerts, film screenings, etc. The building also houses the artistic café, Młody Byron.
