Big exhibition space in the EUR district, which is well worth a wander around if you're in Rome and have some time on your hands. The lego expo is there this weekend, incredible works by lots of different enthusiasts from around the world. My favourite was the 4th century model of Rome, 300,000 bricks and 4 years in the making. Quite incredible, and the chap who did it, very pleasant and humble. The St. Peter's Basilica was also amazing. Lots there to suit all types of lego enthusiast, and even those, like me, who aren't really into it themselves will be pleased they went.
