Some things really are awesome.

LEGOLAND Discovery Center Boston, which opens May 23 in Somerville’s Assembly Square, has made a LEGO version of our beloved Fenway Park. It will be unveiled this Sunday as part of the grand opening of the Kids Nation Clubhouse, a new hangout space in the real Fenway Park for young Red Sox fans.

The model is 4 feet by 4 feet by 18 inches, took 450 hours and 28,000 LEGO pieces to build, and is filled with a throng of 800 cheering mini-figures. The Discovery Center release a delightful time-lapse video of its construction today, complete with a spirited Western-style soundtrack.

Once the Discovery Center opens, the miniature ballpark will become a permanent fixture of MINILAND, a replica of the Boston area featuring mini versions of the city’s most recognizable buildings and landmarks.

The Discovery Center’s “Master Model Builder” Ian Coffey, who snagged the job after winning a two-day “Brick Factor” competition at the Boston Public Library in January, said the LEGO Fenway Park, cool though it may be, is just a minuscule preview of the awesomeness to come.

“I can’t give it away, but it’s really cool,” said Coffey.

LEGOLAND Discovery Center, which is expected to draw crowds from far beyond Boston, is a key component in the drastic redevelopment of Assembly Square into Assembly Row, a $1.5 billion project that will also include upscale shopping and restaurants, housing, offices, and public spaces, as well as a brand new stop on the Orange Line.

Correction: The original version of this article erroneously stated that LEGOLAND Discovery Center will take the former location of Cavalia, the Cirque du Soleil horse circus. We apologize for the error.
