Alien architecture

It's surely impossible to capture this cathedral with a single photo. The outside was a little marred by the scaffolding as they still have towers to complete but inside has much less disruption. In fact it's a little mind boggling. Your eyes get lost in the architecture. You could just sit here all day admiring the complexity. They say Gaudi designed with 3D models and not drawings. He sculpted this design. Although who knows how much interpretation there has been in the near century since his death. Really it's something that wouldn't be out of place on the set of Alien or Lord of the Rings.
