Abstract
Durability differences of 2 types of brick from Santa Maria de Jesus Chapel (Sevilla) and 2 treatments for its restoration have been studied. They have been characterizad using XRD and SEM, as well as their physical, hydric and mechanical properties. Samples prepared with bricks from the chapel have been submitted to salt crystallization test, to identify decay causes and mechanisms. The red brick present the lowest firing temperature, lower porosity and a great proportion of micropores. Physical and mechanical properties don’t change significantly with the treatments, only hygric properties vary with the water repellent. The accelerated aging test revealed significant improvement in the behaviour of yellow brick, but no change in the decay mechanism of red brick (Typical of microporous materials) or its durability is observed.

Summary
One of the Seville’s main institutions for higher studies, Santa María de Jesús College, the kernel of its present university, was founded in 1506 by Rodrigo Fernández de Santaella. Over the years, building use has been adapted as needed. When acquired by the Cathedral Chapter, it was converted to a seminary. The college building was demolished in the early twentieth century to widen Constitution Avenue and Jerez Gate. The chapel was left intact with the exception of the flooring, which was either replaced or covered over in 1963. The chapel and adjacent new building today house the headquarters of the General Council of Confraternities
