Initially established as the association Det gamle Christiania, the museum has evolved over the years, culminating in its amalgamation with Oslo Museum in 2006.

Led by the visionary architect Fritz Holland, the museum’s committee boasted eminent personalities such as Bishop Anton Christian Bang, architects Torolf Prytz and Harald Olsen, artist Eilif Peterssen, and military officer Thomas Heftye.

The significant milestone in the museum’s journey arrived in 1909 when it found its permanent home at the iconic Frogner Manor. With its sprawling grounds and exquisite architecture, the manor provides an ideal setting for the museum’s extensive collection. From art and culture to historical artifacts, Oslo City Museum showcases the rich heritage and vibrant spirit of Oslo.

What sets Oslo City Museum apart is its private association heritage, which lasted until the end of 2005. This unique background adds a touch of exclusivity to the museum, making it a cultural gem adored by locals and tourists alike.
