What was a walkway used in the 17th century by the nuns of the ”’Convento de Santa Catalina”’ to cross over 5A? Avenida Norte from their cloisters to the parochial school without having to venture into the dusty street, is now ”the” clichA tourist photo op in Antigua. And with good reason a the Arco de Santa Catalina is a lovely sight indeed, crowned by a clock tower that was added a bit later, in the 1830s. Today, the arch is looked after by the Santos family, owners of the nearby jewelry store ”’Reino del Jade”’ and ”’Hotel El Convento”’.
