to the well. There are ten stone steps that lead to the actual water level, which was contained within a small stone-and-concrete arched chamber. During the typhoid epidemic of 1920, the well was closed due to sanitary concerns. During the 1977–85 renovations, it was cemented over and decorated with broken tiles from the Camarín de la Virgen. In 2011, the Pozo de la Virgen was reopened after 92 years of being hidden from the public. Convent and patio Adjoining the Santa Ana church is the convent, which was also built on the same period as the church under the direction of Fr. Vicente Inglés. The ground floor is a stone and clay tile cloister surrounding the grassy patio. Above the cloister is a wooden corridor with capiz and glass windows and high doors leading to the priest's quarters, the choir loft and a room previously used as a library. In 1966, archaeological excavations have been conducted by the National Museum of the Philippines on the patio and the churchyard, uncovering 71 human burials dating around late 11th to 14th centuries from the associated Chinese ceramics recovered with the graves. The bulk of data gathered regarding the pre-Hispanic culture of Santa Ana (the ancient Kingdom of Namayan) led to the construction of a site museum in the patio, which was later declared as a National Cultural Treasure in August 1973 by the virtue of Presidential Decree No. 260. Historical and cultural declarations The Santa Ana Church has been designated by the National Historical Commission of the Philippines (then Philippine Historical Research and Markers Committee) as a Historic Building in 1936 with a historical marker for being the first Franciscan mission established outside Manila. The Santa Ana Site Museum located in the convent patio and the Camarín de la Virgen was declared as a National Cultural Treasure in August 1973.
