The Santa Catalina Arch is a historic landmark located in Antigua, Guatemala. It is one of the city's most iconic symbols, spanning across Fifth Avenue North. Originally constructed in the 17th century as part of a convent, the arch was built to connect the convent's buildings so that cloistered nuns could pass from one building to the other without going out on the street. Today, it is a popular tourist attraction and a picturesque spot that often features in photos of the city, especially with the striking backdrop of the Agua Volcano.
