Some of the world's most famous structures are here in Tulsa, well at least in LEGO form?
This is the annual "Brick-Universe" LEGO Fan Convention at the Cox Business Center.
The event brings all things LEGO to Tulsa and people from across the United States as well.
Some of the builders say they've been doing this for years.
Rocco Buttliere, Brick Universe 2018
"I've been building with LEGO for as long as I can remember, I got my first Harry Potter set at the age of 6 and since then kept building. At 14 I started building these models."
If you missed out on the fun today, the convention continues tomorrow from 10 a.m.-4 p.m.
Tickets are $15 online and $18 at the door.
