Daily Spaceship Church – Although still incomplete after 100 years of construction, the church is nonetheless a registered UNESCO World Heritage Site. Designed by Gaudi. There are many wondrous buildings designed by Gaudi in Barcelona. I visited this church in 1992 and climbed one of the magnificent spires. It was a misty day, and at height, much of the modern city was shrouded in fog. I urge you to visit this building. It is monumental and weird.
