Waikiki and Honolulu architecture is an interesting mix of old and new, with beautiful older buildings alongside mammoth high rise hotels. One of the most beautiful buildings in Waikiki is the  Royal Hawaiian Hotel  , also known as The Pink Palace. As newer buildings surround it, and the trees in its own courtyard dwarf it, the hotel is most easily seen from the oceanfront side now. The Royal Hawaiian was built in 1927, it's constructed from sandstone blocks, finished with stucco, in a Spanish or Moorish style. It was the height of grandeur and luxury when it was built and is still quite a grand sight to see. During WWII, the hotel served as an R&R facility for Naval personnel. Honolulu has also great new buildings such as the Trump International Towers in Waikiki
