English: The Santa Catalina Arch is one of the distinguishable landmarks in Antigua Guatemala, Guatemala, located on 5th Avenue North. Built in the 17th century, it originally connected the Santa Catalina convent to a school, allowing the cloistered nuns to pass from one building to the other without going out on the street. A clock on top was added in the era of the Central American Federation, in the 1830s. Source: en.wikipedia.org/wiki/Arco_de_Santa_Catalina

In the background is Volcán de Agua (also known as Hunahpú by Maya) is a stratovolcano located in the departments of Sacatepéquez and Escuintla in Guatemala. At 3,760 m (12,340 ft), Agua Volcano towers more than 3,500 m (11,500 ft) above the Pacific coastal plain to the south and 2,000 m (6,600 ft) above the Guatemalan Highlands to the north. It dominates the local landscape except when hidden by cloud cover. The volcano is within 5 to 10 km (3.1 to 6.2 mi) of the city of Antigua Guatemala and several other large towns situated on its northern apron. These towns have a combined population of nearly 100,000. It is within about 20 km of Escuintla (population, ca. 150,000) to the south.
