Basilique Notre-Dame de la Miséricorde, Minor basilica in Tetuán district, Madrid, Spain.

The Basílica Hispanoamericana de Nuestra Señora de la Merced occupies a Latin-cross plan on Calle de Edgar Neville in Tetuán. Its main façade sets a large concrete arch framing a vertical grid of glass over three doors. The dome rises more than 20 metres above the crossing, and the walls are clad in prefabricated concrete blocks about 40 cm long and 8 cm high. Two planned towers were never built for lack of funds.

The plans by Francisco Javier Sáenz de Oiza and Luis Laorga won the 1949 competition unanimously. Work began that year but was halted for long periods and modified for economic reasons, including replacing concrete arches with a visible metal roof structure. The basilica was inaugurated in 1965 after 16 years of construction, and the two architects, who were friends, ended up falling out.

Ten side chapels, five per aisle, hold Marian images from Spanish-speaking countries: Guadalupe of Mexico, the Virgen de los Treinta y Tres of Uruguay, the Virgen del Carmen of Chile, the Virgen de la Nube and Señor de los Milagros of Peru, and the Virgen de Chiquinquirá of Colombia on the left; Coromoto of Venezuela, the Caridad del Cobre of Cuba, the Virgen de El Quinche of Ecuador, the Inmaculada Concepción of Spain and the Virgen de la Merced on the right.

The basilica stands at Calle de Edgar Neville 23 in the Cuatro Caminos area of Tetuán, a short walk from the surrounding streets. The main entrance is framed by a large concrete arch above three doors. The crypt lies beneath the nave and the parish house and convent stand behind the apse.

The interior ceiling displays an exposed metal framework supporting glass panels, a departure from typical church construction of its era. This modern approach allows light to filter through in unexpected ways, shaping how the space feels.
