Colombischlössle Freiburg, Archaeological museum in Freiburg im Breisgau, Germany.

Colombischlössle is an archaeological museum housed in a neo-Gothic structure distinguished by its glass cupola and detailed interior flooring. The collection spans multiple floors displaying regional artifacts from various historical periods.

Countess Maria Antonia Gertrudis de Colombi y de Bode (1809–1863) commissioned the villa as her widow's residence; it was built 1859–1861 to plans by Freiburg architect Georg Jakob Schneider, who took the English medieval Tudor Gothic style as his model, following his teacher Friedrich Eisenlohr's rebuild of Ortenberg Castle. The city bought it in 1899; it housed the municipal art museum from 1909 to 1923, then served as offices, and from 1947 to 1952 as the seat of the Baden state chancellery under Leo Wohleb. Since a 1983 conversion it has held the archaeological museum.

The name comes from Countess Maria Antonia Gertrudis de Colombi y de Bode (1809–1863), who had the villa built as her widow's residence. The park has served as a meeting point for Freiburg's gay scene and, because of its proximity to the main station, for the drug scene; a drug contact centre was set up in Rosastrasse despite residents' legal challenge. From 1998 to 2014 a mirror tent stood over the fountain from November to January, hosting nightly dinner shows with variety acts.

The park is open to the public since 1906 and covers 1.3 hectares after the Rotteckring expansion of 1962 cut it down from 1.5. Since the Rotteckring redesign of March 2019, tram line 5 stops at Fahnenbergplatz nearby, where a Frelo bike-share station also stands. A low wall along the Rotteckring replaced the earlier one-metre wall, giving seating facing the street.

The basement rooms contain an uncommon collection of Alemannic grave goods rarely displayed elsewhere. These findings offer insight into the daily life of this region's early inhabitants.
