Maurice Packham writes about the historical importance of the flint wall marking the boundary of Brighton and Rottingdean (Letters, November 20).

Unfortunately, demolition is legal because the wall is neither listed nor in a conservation area. The only way demolition could be prevented is for English Heritage to spot-list it or for the owners to feel such shame at spoiling the townscape that they have a change of mind.

Mr Packam is incorrect in saying that the Central National School, a magnificent Regency Gothic building in Church Street, was demolished to make way for a car park.

It was demolished for road widening, which has never taken place. Just before demolition took place, it was spot-listed but as this was during a postal strike, the listing document remained in London while the building was demolished in Brighton.

A council or English Heritage officer could have collected the listing document and saved one of Brighton's most important and beautiful buildings from demolition.

The council-owned Birdcage Bandstand on the seafront, Blues And Buffs (a flint building now without its roof) and the bus shelters in the Old Steine are all listed buildings but have been left to deteriorate into a condition which would not have been permitted had they been privately owned.
