Brick by brick, the famed Castle comes together in this Smithsonian Castle Mini Building Blocks Kit. Little architects plan, stack and maneuver the pieces to build a replica of the Smithsonian Institution's Castle. Built in 1855, the Castle is home to the Smithsonian Visitor Center. The mini building block kit is both a hands-on toy and a sweet way to honor the Smithsonian's 175th anniversary.

Customer Rating: 5 out of 5 A fun project

As I have said in previous reviews of Smithsonian's Mini Block items, these are really fun to construct. Yes, they are more of a challenge than Legos because of the small block size and instructions that are different than Lego. But, the challenge is part of the fun, and the finished items look great. I think most children will need the help of an adult during construction. However, that is part of the fun also!

My granddaughter is a genius. She assembled the entire 668 piece puzzle in 4 - 5 hours!
