Based on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.

How we estimate times · sources and method

A large architectural model with extensive repetition. Familiar builders may speed through repeated modules; finding pieces and checking alignment can take longer for someone starting out.

Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.

BEYOND THE BRICKS

Did you know?

The model, the history, the ideas

Inside the set

An idea years in the making

Rok Žgalin Kobe had been experimenting with the Colosseum at different scales since 2012. The eventual prototype also passed through Mike Psiaki’s hands before returning to Rok for the final design.

Roller skates among the columns

The scrolls on the column capitals use an unexpected element: upside-down LEGO roller skates. At its November 2020 launch, the 9,036-piece model had the highest piece count of any LEGO set.

Beyond the set

The stories, places and inventions behind your build.

A name borrowed from a statue

Originally called the Flavian Amphitheatre, the Colosseum takes its later name from the Colossus of Nero, a huge statue that stood nearby, rather than simply from the building’s size.

Before the arena, there was a lake

The amphitheatre was built on the site of an artificial lake in Nero’s Domus Aurea. Construction began under Vespasian; Titus inaugurated it in AD 80 with a hundred days of games.

SET THE MOOD

A soundtrack for your build

Colosseum · Selected for the building rhythm

For a project spread over several sessions we choose a relaxed ambient backdrop rather than matching the set’s name. The piano alternative adds a more distinct melodic presence.

OUR PICK

Ambient 1: Music for Airports

Brian Eno

Ambient · minimal and relaxed

Spotify ↗Apple Music ↗

Try a different atmosphere

ANOTHER MOOD

In A Time Lapse (Reimagined)

Ludovico Einaudi

Piano · melodic and intimate

Spotify ↗Apple Music ↗

A build to spread over several sessions: choose the more understated option when you want the instructions to take centre stage. The music does not set your pace.
