Over 70% of the monasteries built in the 16th century are still in good condition. However, there are claims that the money allocated for the restoration work is insufficient for the job and far less than has been budgeted for other landmarks such as the Basilica of Guadalupe or even the Palace of the Marqués del Apartado. Much of the work that has been done involves restoring the atrium areas, processional corridors and the atrium chapels, where they still exist. Another major effort is to rid the buildings of moss and plants growing on the buildings themselves. Restoration work in a number of the monasteries and restored, and in some cases, led to the rediscovery of murals. However, much restoration work still needs to be done.
