Only took two and half months , but I finally visited one of the most important (and touristy) sights in Abu Dhabi - the Sheikh Zayed Grand Mosque, which is in recognition of the UAE's founding father who passed away in 2004 (his grave is on-site, but pictures are strictly prohibited).
I've been to a mosque or two previously (i.e. the historic Blue Mosque in Istanbul) and the Grand Mosque here is quite a bit different. Although the Grand Mosque lacks any real historic feeling, it certainly replaces any void with sheer wealth. Think 44 million Svorski crystals used in the 7 chandeliers, which are 9 tons each...think gold plated minarets...think stone and marble sourced from Morrocco, Italy, China, and nine other countries. Moral of the story: a penny was not spared when building the Grand Mosque. Regardless, this is certainly a must-see for any visitor passing through Abu Dhabi - glad I finally did!
