Do you love old buildings that once served a completely different purpose and now surprise you with an entirely new concept? Then you’re in luck, because Berlin has plenty of them. From a former pharmacy that now houses a chocolate shop to a coffee and brunch spot in a former Shell gas station —there are special stories behind these places. And now there’s an absolute highlight to add to the list: THE KNAST at Söhtstraße 7 in Berlin-Lichterfelde. The historic complex was built between 1902 and 1906 to serve as a district court and a women’s prison.
The complex was designed by architects Rudolf Mönnich, Walter Sackur, and Paul Thoemer. The women’s prison was in use for more than a century before finally closing in 2010. Today, the historic complex is gradually being transformed into an extraordinary adults-only destination that combines a hotel, fine dining, a bar, art, culture, and events . On September 15, 2026, THE KNAST will officially open its hotel section as an adults-only boutique hotel. Initially, nine rooms—converted from former prison cells—will be available. Four additional suites on the top floor are still under construction, one of which will even feature its own terrace overlooking the garden.
The building’s past is by no means hidden; rather, it’s deliberately integrated into the concept. THE KNAST refers to its hotel rooms as “cells.” Guests can choose from different categories. The single cells range in size from 16 to 23 square meters, the twin cells from 14 to 19 square meters, and the double cells from 19 to 24 square meters. There is also a 31-square-meter junior suite. In some cases, several former prison cells were connected to create these suites. In some rooms, original barred windows still serve as a reminder of the building’s former use.
One of the most unusual areas of THE KNAST is located in the former chapel of the women’s prison. Where church services once took place, there is now a speakeasy bar. The menu features, among other things, signature cocktails, classic whisk(e)ys, non-alcoholic drinks, and special absinthe rituals. Fuchs & Hase and bartender Mike Meinke are behind the bar concept. In keeping with the mysterious speakeasy atmosphere, the bar enforces a strict no-photo policy. This is intended to protect guests’ privacy and ensure an undisturbed experience within the historic premises. The bar is currently open Wednesdays and Thursdays from 6 p.m. to 11 p.m. and Fridays and Saturdays from 6 p.m. to 1 a.m.
THE KNAST’s restaurant is located in the prison’s former administrative wing and is also reserved exclusively for adults. Executive Chef Michael Zscharschuch oversees the kitchen. In addition to à la carte dishes, guests can choose a custom-designed four-course or six-course menu .
Not all of the former cells are used for the hotel or dining facilities. Some have been converted into studios for artists. Among others, the nonprofit organization prideART Berlin has found a home here . Workshops, exhibitions, and other cultural events take place in the historic rooms.
In fact, art plays a central role in THE KNAST’s concept. The program ranges from exhibitions, opening receptions, and musical performances to burlesque, rope art (or shibari), and kink comedy. THE KNAST sees itself as an open and tolerant cultural venue with a queer ethos. Today, the former prison complex is thus far more than just a hotel or restaurant, combining dining, lodging, art, and extraordinary events in a single historic location.
