Sometimes good ideas have bad results． This is what happened to Spain's Matrera Castle （城堡）． The castle was built in the 9th century and has interested thousands of visitors every year． But part of it broke after a heavy rain， so the castle needed a big repair． However， the result didn't turn out well． The castle became a totally modern building!

"The building has nothing to do with what it used to be， or even with a medieval （中世纪的） castle，" criticized （批评） the Spanish cultural heritage group （文化遗产组织） Hispania Nostra． People across the world have been laughing about it online too． "How terrible!" "They've got builders rather than repairers．" "No words are needed when you see the pictures．"

The leader of the repair said that he wanted to make sure the building stayed standing． Facing the criticism， he also added， "Opinions are always welcome．"
