The sculptures are built of stucco and are unusual in Maya art for being in-the-round. Open to the public. www.yucatantoday.com/en/topics/ek-balam According to a scholar's website: "The ancient Maya preserved the stucco so well that no modern restoration was required. Not long after Ukit Kan Le'k Tok' was buried inside the building, it was carefully filled with powdered limestone and rocks and then the entire facade was covered with the same material." So the sculptures are original and have not been restored. www.mesoweb.com/features/ek_balam/index.html
