14. Al Ashrafiya Mosque
The Al Ashrafiya Mosque is one of the most important mosques in Taiz, Yemen and it was established sometime in the 15th century. Since then, this olden mosque has been well-preserved and each time it was restored, a new phase or design was added. It has experienced severe chemical cleaning methods like Ammonium Carbonate solution just so to wash out the century old superficial filth. After the cleaning system, one can see the beautiful Arabic-inspired mosaic art and drawings in gold and red vibrant colors.
