Villahermosa del Río is the small town where the hermitage (late XIII or INTRODUCTION early XIV century) of San Antonio Abad is located. It houses the recent discovery of a tempera wall painting of the last third of the fifteenth century. During its architectural restoration, due to suspected remains of oldest painting, but with no information about them in the documents consulted, it was decided to conduct a series of studies to verify the existence or not of underlying paintings with special photography techniques.

METHODOLOGY Before and during the restoraWon process, these studies have been conducted by taking micro-‐samples, subsequent laboratory analysis and the use of special photography techniques such as ultraviolet fluorescence, infrared photography (with several wavelengths) and visible light (macro photography, fluorescence, tangenWal light…), in addiWon to image processing that has provided very useful informaWon for the detecWon of hidden painWngs under the repaint and during the restoraWon process, studies have been conducted by taking micro-‐samples, subsequent laboratory analysis and the use of special photography techniques such as ultraviolet fluorescence, infrared photography (with several wavelengths) and visible light (macro photography, fluorescence...), in addiWon to image processing that has provided very useful informaWon for the detecWon of hidden painWngs under the repaint.

The RESULTS of these techniques, used as a method of nondestrucWve analysis, These photographs have provided informaWon regarding, among CONCLUSIONS confirmed the presence of oldest painWng and, aYer exhausWve documentaWon, the restoraWon of the panel located opposite the main entrance was performed. The first cleaning tests uncovered the boZom part of the central figure and, as the processes conWnued, it became possible to see a scene with three saints: Saint Christopher, Saint SebasWan and a figure sWll unidenWfied.

In addiWon, photographs have allowed to keep record of the different processes in the panel conservaWon and restoraWon and will be a valuable aid in all processes.
