Location Information:
he nave is open and circular, surmounted by a dome. The dome contains sixteen circular stained glass windows. The fifteen spaces between these windows signify the fifteen decades of the traditional rosary.
The nave is surrounded by fifteen smaller side chapels, one for each of the traditional Mysteries of the Rosary. On the left of the nave are found the Joyful Mysteries; in the centre behind the sanctuary are the Sorrowful Mysteries, and to the right are the Glorious Mysteries.
Each side-chapel comprises a large mosaic with a central image depicting the theme of that Mystery, and an inscription in Latin. Incorporated within the larger image may be smaller images of related themes. For example, the side chapel directly behind the altar contains a depiction of the Crowning with Thorns, which is surmounted by an image of the Ark of the Covenant (see figure).
Most of the mosaics bear a date of around 1900. In each side-chapel is a small altar bearing six candles.
