(Tribune Media Services) -- We don't know where to look first. The massive pillars, looking like tree trunks, stone chameleons, tortoises and turtles, help support the columns. The sheer size of the place is amazing. Some of the towers soar more than 500 feet. Even jaded teens, like my 13-year-old niece, Erica Fieldman, can't help but be impressed. Antoni Gaudi's Sagrada Familia is Barcelona's most famous site and Spain's most visited. Welcome to Antoni Gaudi's unfinished masterpiece, the Sagrada Familia, Barcelona's most famous site and Spain's most visited. More than 40 years after the eccentric and revered architect's death -- he was struck by a tram -- work still continues on the huge church first begun in 1882. Some 2.5 million people visited last year.
