The schools were chosen by a panel of judges from a list of 1,500 to create their very own royal-themed bench, which will placed inside the attraction in the run up to 6 May.
The winning bench in Northern Ireland will be displayed at Hillsborough Castle and Gardens.
The benches will remain in the Tower of London throughout the summer, before being transported to the winning schools "as a lasting legacy of the Coronation."
From climate change to unity and peace, each bench is inspired by issues that matter to children and young people.

Booker Avenue Infant School, in Liverpool, is one of 15 schools selected for the honour. They say they were inspired by their own Plant a Tree for the Queen's jubilee campaign.
‘The More We Know. The More We Grow’ is the primary school's ethos and it is reflected in their colourful tree design.
A spokesperson from Booker Avenue said: "Our school community care deeply about environmental issues and have a strong desire to actively protect our planet."
