The museum was first conceived in the early 1920s during the final years of Bishop Ġwanni-Marija Camilleri's tenure. To create space for the museum, several storerooms at the back of the cathedral were demolished, and two halls were constructed. However, interest in the project waned during the subsequent bishoprics of Michael Gonzi and Joseph Pace.

The appointment of Bishop Nikol Cauchi in 1967 revitalized the museum project. The Cathedral Chapter unanimously approved the plans on February 9, 1969, for the museum to be situated on the originally intended site. Master mason Karlu Vella began construction on November 2, 1970, following a design by architect Joe Dimech, with the interior crafted by arts master Carmel Grech. Although construction took longer than expected, the museum was inaugurated on October 21, 1979.

The need for a complete refurbishment of the museum was recognized, and the project commenced in September 2018. During this time, all exhibits were stored to allow for renovations, which were supervised by Joseph Calleja and co-financed by EU funds and the Gozo Cathedral Chapter.

The revamped museum is spread over three levels, accessible by stairs and lift. The Silver Vault on Level 1 displays a vast array of ecclesiastical silverware, including a beautiful solid silver crucifix and 12 matching candlesticks used on the cathedral high altar during the feast of Santa Marija. These items, commissioned in Germany in 1914, were delayed during World War I and only arrived in Gozo in 1920.

Level 2 houses the History and Memorabilia section, featuring items that portray the history of the cathedral, including the former landau of the bishops of Gozo. This vehicle, assembled in the early 1860s, was donated to the diocese in 1864 and used until 1945 on special occasions. The museum offers a rich insight into the history and ecclesiastical heritage of Gozo, making it a significant cultural attraction.
