Our Lady of Fair Haven Cathedral is the principal Roman Catholic cathedral in Roseau, Dominica, and serves as the seat of the Diocese of Roseau. Located on Virgin Lane in the heart of the capital, it is one of the city's most recognizable religious and historic landmarks. 

The cathedral traces its origins to an earlier church established during the colonial era. The present structure is known for its Gothic and Romanesque influences and was built using local volcanic stone, reflecting both European architectural traditions and Dominican materials. Historical accounts note that the church evolved from an earlier timber building before later expansions and reconstruction. 

As the cathedral church of the Diocese of Roseau, it functions as the spiritual center of Roman Catholic life in Dominica. Major diocesan liturgies, celebrations, and religious observances are associated with the cathedral. The church is dedicated to Our Lady of Fair Haven, a title of the Virgin Mary with longstanding importance in the island's Catholic heritage. 

Visitors often highlight the cathedral's imposing stone exterior, historic character, stained-glass windows, and traditional furnishings. Even during periods of restoration, travelers have described it as an impressive landmark and one of the notable sights in Roseau. The cathedral is frequently included among the city's religious and cultural attractions. 

The cathedral has undergone extensive restoration and reconstruction work over several years. Reports and visitor reviews frequently mention ongoing renovations intended to preserve the historic structure and address damage accumulated over time. Restoration efforts have been significant enough that access has occasionally been limited during construction phases.
