Igualada Cemetery, outside Barcelona, Enric Miralles. Visited this place many years ago, and it has always stuck in my mind. Marries the analogy of post industrial decay & death, but does so in a truly thoughtful way without being macabre.
From the Greenwich Observatory - Canary Wharf forms the backdrop for the Old Royal Naval College, Greenwich, London, UK. Best way to get there is the ferry along the thames. Also close by is the Virgin Air Walk gondola across the thames
