After her death, the remains of Queen Constance were buried in the Royal Monastery of San Benito in Sahagún, where King Alfonso VI of León and Castile and several of his wives had been buried. The remains deposited in a sepulcher, which was placed on the cruiser of the monastery church, next to the graves containing the mortal remains of the wives of Alfonso VI. Her grave had to be destroyed either during the fire that the monastery suffered in 1810, during the Napoleonic invasion of the War of Spanish Independence or during the exclaustration and confiscation of the Royal Monastery of San Benito, carried out in 1835.
