You needn't be religious to appreciate the calming atmosphere of St. Josephs Cathedral. Look up when the next service starts or when it's open for general viewing.
St. Joseph's Cathedral is a worthwhile place to start out your day in Abu Dhabi City Center. This principal church comes recommended by fellow travelers, but it's not the only spot to see here. Allow some time for other sights like Abu Dhabi Mall, Marina Mall, and Zayed Sports City Stadium to get a complete picture of what's on offer in the area.
