When Sigmund Freud moved to the newly built building in 1891, the previous building on the site, once owned by Victor Adler, was demolished. The building, where Freud lived and wrote for 47 years, now houses a documentary center displaying his life and works.

The museum encompasses Freud's former practice and private quarters, which are attached to Europe's largest psychoanalytic research library containing 35,000 volumes, and the research institute of the Sigmund Freud Foundation. The display includes original items owned by Freud, his waiting room, and parts of his antique collection. Although Freud's famous couch and most of the original furnishings are in the Freud Museum in London, a third museum in the Czech town of Příbor was opened to the public in 2006 in the house where Freud was born.

The Sigmund Freud Museum is housed in a magnificent 19th-century building that was newly constructed in 1891. It was built in a neo-renaissance style, typical of the buildings in Vienna during that time period.

The building itself is a work of art, with ornate sculptures and intricate details on the exterior. The interior is just as impressive, with high ceilings, grand staircases, and large windows that let in ample natural light.

The building has undergone renovations and expansions over the years, with the most recent expansion taking place in 1996 to accommodate new rooms for special exhibitions and events. Despite the changes, the original architecture has been preserved and can still be seen throughout the museum.

Visitors to the Sigmund Freud Museum can admire the beautiful architecture and explore the building's history while learning about the life and work of the famous psychoanalyst who once called it his home.
