Our Lady of Mercy Church. Havana.
Main altar decorated for a wedding.

"... founded around 1755 and only officially blessed in 1792. The later construction is clear in the baroque façade while an extensive rebuilding in the 1860s transformed the relatively poor church and convent into one of the most richly decorated temples in Cuba – full of paintings by well-known artists and elaborate embellishments.

"The Our Lady of Mercy Church in Old Havana dates back to the 18th and 19th century and was built by the Mercedario Fathers who immigrated to Cuba from Catalonia. 

Their assets were expropriated by the Medizabal government and expelled from Cuba in 1841. Thus they had to abandon their monumental work, leaving it half finished". Description from Havana Times.org.
