New Cathedral of Cuenca, Roman Catholic cathedral in central Cuenca, Ecuador.

The New Cathedral of Cuenca is a Roman Catholic church in the historic center of Cuenca, Ecuador, recognizable by three blue domes rising above the rooftops of the old town. Inside, tall vaults, marble columns, and many glass windows cast the nave in shifting colors.

Bishop Miguel León Garrido ordered the foundations opened on 2 October 1885, and the first stone was laid on 12 December 1886. The plans were drawn by Juan Bautista Stiehle, a German-born friar who had come to Cuenca from Alsace in 1873. Work advanced in stages for roughly a century, with interruptions such as the stoppage of 5 June 1903 caused by money and material shortages, and was completed in the 1980s.

The name Cathedral of the Immaculate Conception refers to a Catholic doctrine honored here through liturgical celebrations and processions. Visitors often see locals praying before side altars or lighting candles as colored light filters through the windows.

The cathedral stands in front of Parque Calderón, between Mariscal Sucre, Simón Bolívar, Benigno Malo and Padre Aguirre streets. The towers were left truncated because the foundations could not bear their planned height, so there is no tower climb; the entrance is reached by three stone steps.

The crypt beneath the cathedral measures 96 metres long, 12 wide and 4 high, and was among the first parts built: work began there in 1885, before the first stone was laid on 12 December 1886. It can hold up to three thousand people. The two front towers were meant to carry domes, but construction errors stopped them.
