THE Sydney Opera House and other tourist attractions around the world are set to be immortalised in Lego.

New York's Empire State Building and Seattle's Space Needle are also among the seven brick-built models in the new architecture range, which is due for launch in Australia in March.

The Opera House model, which will cost $59.99, is made of 260 Lego bricks.

Designed by Danish architect Joern Utzon, the Sydney Opera House was declared a UNESCO World Heritage Site in 2007.

Lego Australia's director of marketing Caroline Squire said the range aimed to interpret the designs of renowned architecture from around the world.

Each model comes with a booklet featuring step-by-step building instructions, archival history, information and photographs of each iconic building, its design origin, architect and architectural features.
