The new monastery and the new church of the Order of Montesa were built during the years 1761-1770 by order of Carlos III, after the earthquake that destroyed the castle of Montesa and demolishing the old medieval buildings that had belonged in their day to the Order of the Temple, located in this square. Its style is neoclassical.

After the War of Independence, the monastery was abandoned, being used later by various administrations. It is currently the seat of the Government Delegation.
