Gold-domed is a descriptor that can be used to describe a building, often referring to the dome at the top of the structure that is covered or painted in gold. However, if you are looking for alternative synonyms to replace this descriptive term, you might consider words such as gilded, golden-topped, or gold-capped. These words still convey the same essence of beauty, elegance, and luxury that the term gold-domed does, but with slightly different connotations that may suit your needs better. Other descriptive words that can be used instead of gold-domed include gold-covered, gold-plated, and gold-finished.
