The Burj Al Arab, Dubai, UAE

Often dubbed 'the world's only seven-star hotel' (erroneously, as official rankings stop at five), the Burj Al Arab is one of Dubai’s most iconic structures, and goes a long way to earning its nickname. Resembling a billowing ship's sail, it stands proudly just off the Dubai shoreline and is best seen from Jumeirah Beach at sunset, when the skies turn all shades of pink and orange.
