This is Sevilla's Metropol Parasol. Officially the largest wooden structure in the world, it debuted recently to mixed reviews both by residents and visitors of Southern Spain's largest city. The Metropol Parasol has a walkway and an observation deck, as well as restaurants, bars and a farmer's market.

Did we mention that the whole thing is held together by glue? Hopefully it can withstand Sevilla in the summer.
