1. Arco de Santa Catalina
The Arco de Santa Catalina is the most photographed structure in Antigua Guatemala, and for good reason. This yellow arch spanning 5a Avenida Norte was built so the cloistered nuns of the Santa Catalina convent could cross the street without being seen by the public. After the 1773 earthquakes damaged the convent, the arch was abandoned for over a century before being restored in the 1890s, when a clock tower was added on top. Today it frames a perfect view of Volcan de Agua at the end of the street. The arch is free to see and accessible 24 hours a day since the street runs right through it. It's a must-see in Antigua Guatemala, but be honest with yourself: it takes about two minutes. Walk through, take your photo with the volcano in the background, and keep going. La Merced Church is a two-minute walk north from here, and Parque Central is an equally short walk south. The arch works best as a landmark on your way between the two. What makes it worth stopping for is the street itself. 5a Avenida Norte between the arch and the park is lined with restaurants, jade shops, and coffee roasters. It's the main tourist corridor, busy from morning to evening. Among things to do in Antigua Guatemala, this is the one you can't miss even if you tried.
