I lifted the photos below from the blog post: http://qal3ataltareekh.blogspot.co.uk/2010/08/blog-post.html?m=1. This blogger went to great effort to post what seem to be more than 100 historical photos of Oman & Zanzibar. Some, I had never seen before. If you're into Omani history or old photos, I recommend checking the post linked above out. From looking at some of the photos, it becomes clear how much Oman has changed in the last half century but maintained her essence.
