👉Gondar Castle’s New Look: A Restoration Raising Eyebrows!
———————————
🏷The restoration of Gondar Castle has caused public curiosity. The castle, known for its yellowish appearance, seems so much whiter now, and many wonder why.
⏺I have visited the castle multiple times and had the opportunity to supervise several conservation studies on it conducted by my MSc students at AAU.
🏷Here are a few points from a professional perspective:
1) Using new lime mortar in the restoration resulted in a generally whiter color, which will gradually turn light yellow over time.
2) The stone surfaces, which algae and lichens had darkened before restoration, were cleaned during restoration, resulting in a new whitish look.
3. The difference in lighting—Pictures taken at different times and in different lighting can significantly change the color.
Limestone buildings turn yellow over time as iron impurities oxidize when exposed to moisture and air
