The building at 104 Donceles Street was originally the home of the Cristo College, founded by Don Cristobal Vargas de Valdez in 1612, when it received its royal charter. No classes were given in this building, but it was still called a college because it offered scholarships for students living there. The college almost closed in 1774 due to lack of funds, and was subsequently merged with San Ildefonso College in 1775. The present-day building was constructed between 1770 and 1780, replacing the one built by Vargas de Valdez. While it has a number of minor alterations over the years it is basically the same Baroque facade and a small patio, and is considered to be a prime example of an 18th-century residence. The facade is of two levels and faced with tezontle, a blood-red volcanic stone. Windows and doors of the main facade are framed with '''', a greyish-white stone. The portal shares similarities with the Colegio Grande portal of the San Ildefonso College, with which this building was associated. The lower arch is flanked by paired columns, which are fluted only in the upper part. The upper level of the portal is profusely decorated with plant designs with
estipite (inverted, truncated, slender pyramid) designs. The cornice is very simple, containing a relief of a crucifix. Upon entering the main door, there is a long, narrow hallway that leads to a very small patio area. ==References==
