The Knights’ Tower
From high above the city (329 ft. at the pinnacle), the bells of The Knights' Tower at the Basilica of the National Shrine of the Immaculate Conception call the faithful to prayer and announce significant events in the life of the church. The tower is an impressive structure – taller than the campanile of the Basilica of St. Mark in Venice (at 325 ft.) and the Leaning Tower of Pisa (at 188 ft.), but shy of the 555-ft. Washington Monument (of course, given the elevation of terrain in northeast Washington, it is nearly the monument’s equal).
