of Puebloan origin. In 1902, Hewett inspected the walls while they were being repaired and noted a few sections that were constructed from 'puddled' adobe, a building technique used by Puebloans before the Spanish introduction of adobe bricks: Based on this work, Hewett concluded that the majority of the building was probably of Spanish colonial origin, but may have been partially built on the foundation of an earlier Puebloan structure. Ralph E. Twitchell believed the building had a Pueblo connection as well: Adolph Bandelier disputed the existence of the Analco pueblo and believed the house to have been constructed in the 1690s. A dendochronology study of the wooden vigas (ceiling beams) in the house reportedly showed they were cut between 1740 and 1767. In 1903, the house became part of St. Michael's College along with the neighboring San Miguel Mission and Lamy Building. At the time, the building was in disrepair: The second story of the house was removed around the same time but was rebuilt in the 1920s, restoring the house to resemble its original appearance. It continues to operate as a tourist attraction, with the interior restored to an approximation of what it may have originally looked like. Architecture The De Vargas Street House is a two-story adobe building; the first floor is original and the second floor was reconstructed based on the original in the 1920s. Most of the house is constructed from adobe brick, which was a Spanish colonial technology, while a few lower wall sections are puddled adobe characteristic of pre-Spanish pueblo buildings. The first-floor ceiling is original and includes vigas dating to the mid-18th century. The first floor interior has two Spanish colonial-style rooms with corner fireplaces, while the second floor is "a dummy" and not open to visitors.
