This elegant palace is on one side of the Plaza of Santa María. It was ordered rebuilt by the Bishop Pedro García de Galarza, at the end of the 16th century, whose shield can be seen over the central window of the second floor. It has an elegant facade with semi-circular arches with a double masonry bolster, flanked by two medallions that represent a man and a woman American Indian.
This palace has two more facades, one from the former Seminary of San Pedro, founded in the 17th century by the same Bishop Galarza and moved here after its demolition; and the other on the street Arco de la Estrella. The location of this beautiful building, the back of which faces onto the city walls and the New Gate, was the cause of legal disputes with the Marqués de la Quinta de la Enjarada to open and remodel the Arco de la Estrella, so his carriages could pass through.
