Carol - you are correct
Casa de las Conchas (House of Shells) was built around 1500.
The builder was a Knight in Order of Santiago de Compostela
The shells are symbols of the Order - There are 300+ on the building.
He was also a professor at the University of Salamanca, which is the third oldest in the world.
Also where I attend a summer program in 1972 that changed my life.
