The Dominican monastery and its Basilica de Nuestra Sra del Rosario y Convento de Santo Domingo (Our Lady of the Rosary and Convent of St Dominic) is located on Defensa 422, the street which hosts the Sunday market which extends for about a kilometer and leads to the famous San Telmo antique fair. The baroque basilica was constructed 1751-1773, using, like so many other churches in Buenos Aires, the Neoclassical barrel vault modified to accommodate large domes. The numerous altars approached by the two side aisles are highly decorated in the Baroque fashion. I found the contrasts in lighting to be severe (dark darks and brilliant yellow-orange lights) and a bit more of a challenge than I could manage to my satisfaction. The ceiling above the right aisle is badly crumbling, so netting is in place to protect visitors and the faithful. Damage is also evident in the nave's ceiling (darkened areas), all of which will be remedied in the fullness of time.
The basilica was shelled during the British invasion of Buenos Aires in 1807. A few 'enemy' flags can be seen in the nave. A monument in the basilica's courtyard (not shown in this blog) serves as a mausoleum for General Belgrano, famed for his leadership in the Argentine war for independence from Spain in 1816.
Strangely, I can find nothing in English about this beautiful church. While not off the beaten path, it is not included in any of our numerous tour books, yet it deserves a visit. If nothing else, it offers a place to sit down to people tired from walking the cobble stone street while visiting the market on Defensa.
