PORTENCROSS Castle has been standing four-square on its rock on the Ayrshire coast for more than 600 years, 250 of them without a roof. It has been ''battered by abrasive, salt-laden winds'' (James Brown's letter, May 22) throughout that period and had its feet in the sea a few times too but has survived remarkably well.

The Portencross Association is completely aware of the urgent need for the building to have a functional roof of some sort to keep out the rain, which appears to be the main enemy, and ongoing repairs to preserve it, hopefully for another 600 years, as a stable ruin.

As far as using public money for this work is concerned, if the public want to see the building preserved as a ruin, which seems to us to be overwhelmingly the case, then why shouldn't their money be used for this? It will be a very wealthy private buyer who does not try to access public money in the form of grants to restore the castle for his own purposes.

The thing about Portencross Castle is that most of us look at it and imagine that we would love to live in it. It is a wonderful option for one household but it is an exclusive option and, by the nature of things, even the most altruistic private owner would be transitory.

It would take a very magnanimous owner to allow the public access over the castle rock and harbour as has been the situation for generations and have the opportunity to ''bring their imagination,'' which James Brown seems to scorn.

Incidentally, it is kind of Mr Brown to have ''the welfare and best interests of the people of Portencross foremost in [his] heart''. We are a small individualistic community here, but we too are passionate about the place and we can think for ourselves, thank you.

If James Brown is seeking support for his wealth-generating plans, perhaps he should be more explicit about them.
