The plans submitted to City of York Council stated there would be no structural changes to the inside of the building, and all alterations would be reversible.
According to the Local Democracy Reporting Service, existing fixtures and fittings would be used to display elements of the proposed gallery and free-standing furniture would be used.
The application stated: “The proposed change of use of Micklegate Bar to an art gallery and shop represents a sensitive, sustainable and heritage-led reuse of this nationally significant structure.”
At least half a dozen reigning monarchs have passed through the famous gateway into the city of York.
By tradition, they stop outside the building to ask the Lord Mayor’s permission to enter.
For centuries, the severed heads of rebels and traitors were displayed above the gate.
Victims have included Sir Henry Purcey (Hotspur) in 1403 and Richard, Duke of York, in 1460.
The last of the severed heads was removed in 1754.
