Rustaq fort, Oman

Rustaq (or Rostaq) was once the capital of Oman. Rustaq fort, built four centuries prior to the dawn of Islam in Oman, is an imposing structure built on three levels, containing separate houses, an armoury, a mosque and four towers. My photo was taken in 1977 - in more recent times, the fort has been renovated. I'm glad I had the chance to see it in its original condition, but renovations were necessary to keep it standing.
