With its anonymous entrance on a rather nondescript street, you could easily walk past this little gem of a church without a second glance, but take a look inside and you will have your breath taken away by the wall-to-wall frescoes by Neapolitan master Luca Giordano which have led San Antonio de los Alemanes to be called "the Spanish Sistine chapel".
