Muscat Doors & Windows

When you are a designer, you don't only look, but you SEE, notice, observe and appreciate. Before I studied design, everything looked fine, but after I delved into the world of design, my eye was trained to see beyond what's on the surface and to find details in everything *MashAllah* In my Muscat trip, something I noticed was their unique doors and windows. Below are a few that caught me and I liked. Most were in the Mutrah Souq area. The last were from the Sultan Qabous Grand's Mosque.  

Which one was your favourite?
