The team behind a huge sandcastle in the Brazilian town of Niteroi hope it will be named the tallest of all time, when a team from Guinness World Records visits the structure.

The 12m (39ft) high castle was designed by American artist Rusty Croft, who builds sand sculptures around the world.

The structure is made up of 20 truckloads of sand and took nearly a week to construct.

Archie Lionce from one of the companies sponsoring the construction said they would find out the result within days.
