RE: the building is quite old but the design is quite stunning

I'm sorry I misunderstood your question, 🙏🙏🙏
first I want to say that Indonesia has many provinces, and each province has a different style and characteristic of architecture, and this building is a hallmark of one of the provinces namely Aceh,
this architectural form and style has become characteristic for Aceh starting from ancient times and is still widely used, I hope you are satisfied with my answer.thanks so much 🙏🙏
