Closed to the public for almost a decade
due to
structural problems, the 16th century Iglesia San José in San Juan,
Puerto Rico, was placed on the World Monuments Watch list of 100 Most
Endangered Sites in 2004. The church is the oldest surviving
masterpiece of Spanish colonial church architecture in Puerto Rico and
one of the earliest extant examples of Gothic architecture in the New World began in 1523. Within
its walls is the 17th century Capilla del Nuestra Virgen de Rosario,
containing the most extensive and possibly earliest murals in Puerto
Rico which were once in a serious state of deterioration. Outside, the
chapel is
distinguished by an ornate sculpted Baroque dome of the same period. In
order to preserve the chapel as a legacy of Spanish Caribbean culture
and as a place of continued use and veneration, the ACL and its
partners embarked on a comprehensive conservation program including
documentation, analysis, and emergency stabilization of the plaster,
paintings and exterior ornamental dome. |

From
May to June 2004 an examination and graphic survey was conducted to
record the materials, methods and condition of the interior of the
Rosario Chapel includind its dome. As part of the documentation process the
chapel was photographed and digitally montaged. Measured CAD drawings
were developed from these rectified images in order to document and
digitize the information recorded from the walls and the ceiling. The
condition survey was then prepared using a glossary developed to
establish a descriptive terminology of the conditions and building /
painting campaigns. This glossary corresponds to the on-site survey and
its digitized format. Painting campaigns were also identified
in
situ and dated through the use of archival documentation and historical
photographs that described the church and it’s interior. The
condition survey of the mural paintings led to the development of an
emergency conservation / stabilization treatment for the areas at
immanent risk of collapse. |
The
scope of work for the treatement included the emergency stabilization
of the mural paintings in the Rosario Chapel using a system of hydraulic lime
injection grouting of the detached areas of the
murals. Treatments
were begun in the most severe areas of detachment which were primarily
located around areas of major loss.
