A colorful Lego house under construction, featuring a red roof and various bricks. Miniature figures are working: one on a ladder painting the house, another using a tool, and a third pushing a wheelbarrow.

Lego bricks as we know them were invented in 1958, after several years of research and development into the material and shape of the bricks.

The bricks of that era can still be used today, along with more recent bricks, to build all kinds of models.
