In the 16th century, during the period of the Spanish conquest of Guatemala, the shore of the lake was the scene of a battle in which the Spanish and their Kaqchikel allies defeated the Tz'utujils. After the Spanish conquest of Guatemala, the Franciscans set up a church and monastery in Panajachel soon afterward, and used the town as a centre to convert the indigenous people of the region to the Roman Catholic faith. The original façade of the church still stands, and is considered one of the gems of the colonial style in Guatemala.
