12 •Eiffel Tower, Lego
Pity poor Gustave Eiffel. He had to build his Parisian tower out of steel. These days, you can construct a replica of the iron icon with the latest landmark kit from Lego: 3,428 pieces, 42½" high when complete (1:300), recommended for enthusiasts ages 16 and up ($200; Lego.com). -- ML
