It's fair to say that a Lego craze has swept across Macarthur.
Close to 4000 kids and young at heart gathered for the inaugural Camden Brick Spectacular on the weekend.
Hundreds of thousands of Lego pieces were joined together to create an array of incredible constructions at the Camden AH&I Hall on Saturday and Sunday.
Highlights included a major medieval layout consisting of more than 100,000 Lego pieces and standing over seven metres high; a major military tribute display; and Star Wars-inspired constructions to celebrate Star Wars Day (May the 4th).
There was also a large play table for children to have a go at creating Lego displays.
Henry and Marielle, contestants from Channel Nine's Lego Masters TV program, also made a special appearance, posing for photos with excited locals.
Event organiser and Lego enthusiast Graham Draper said he was delighted with the crowd numbers on the weekend.
"I am absolutely stoked, at one point people were lined up 60 metres down the road waiting to get in," he said.
"It was an incredible response from the community.
"There was really good displays, I think the general public was blown away with what could be designed."
Mr Draper said more than $5000 was raised during the two-day spectacular. He said funds generated would be spent on Lego sets to go towards a local charity, which is yet to be chosen.
Mr Draper said he would now start planning for the 2020 Camden Brick Spectacular.
