Robots and knights, spaceships and roller coasters.
All of these things and many more intricate creations could be seen in miniature form at Brixhibition 2019.
Lego lovers of all ages made their way around the Albert Hall, enjoying the many elaborate and detailed works of art.
Brixhibition organiser Ken Draeger said the day had been busy but great.
"Lots of new things this year and I think the kids are really enjoying it, the adults too," he said.
"We have a really cool alphabet - a lot of parents love that.
"I like it because it's an original, unique idea that no one had done before."

As expected the large-scale Tasmania replica drew the attention of attendees.
"There was about ten of us that actually worked on it [Lego Tasmania] over two weekends," Mr Draeger said.
"There's maybe 120 hours work in that."
Brixhibitionists from across the state put their creativity to the test, with a number of moving exhibitions including a Stormtrooper assembly line.
"We're always trying to do new things," Mr Draeger said.
"The mosaics are quite popular too and not big so we thought we'd introduce them - anything we think is new or clever we try to introduce."
The school Lego competition champion will be decided Sunday afternoon.
"We would like to inspire kids to go home and build something without instructions and without a kit," Mr Draeger said.
"That's the core thing we're trying to get across."
