Previous cabinet cost £390
A cabinet used to hold the 'letters patent' for granting Douglas city status cost the council £13,000.
The documents are on display in City Hall and were given to the council by Queen Camilla on behalf of King Charles.
It was previously revealed that the local authority spent £5,000 on her visit in March and wasn't given any financial support from government.
An earlier display cabinet for the documents was £390.
