How much did holy-rood cost?

The construction of the Palace of Holyroodhouse in Edinburgh began in the 16th century, and its costs varied over the years due to renovations and expansions. The original building was commissioned by King James IV, but exact historical costs are difficult to determine. Today, it serves as an official residence of the British monarch in Scotland and is maintained by the Royal Collection Trust, which incurs ongoing costs for preservation and public access.
