A pensioner says he will stand in an election to become a councillor unless politicians give more support to his campaign for toilets to be installed at Berkhamsted Castle.
English Heritage, which manages the historic landmark, says toilets would be inappropriate, too costly to install and impractical as the tourism hotspot is not staffed.
The organisation has in the past suggested that people who are desperate use the public toilets at Berkhamsted Railway Station, which are a short walk away.
But John Waller, 69, of Cobb Road, Berkhamsted, has been campaigning for years to make English Heritage change its mind.
He said: “We owe it to the countless mothers and children who visit the castle, not to make them make the dangerous journey onto the station platform, so their loved ones can do what children have done since being put on this earth.”
Mr Waller says that unless Berkhamsted Town Council backs his campaign, he will stand in the next election to become a town councillor himself.
He said: “I will make this public pledge. I will not claim any expenses whatsoever and will walk to the meetings and take my own biscuits and coffee, therefore not increasing council tax or exacerbating parking problems within the town.”
Berkhamsted is where the crown of England was formally handed to William the Conqueror in 1066 after the Saxon army was defeated at the Battle of Hastings.
The castle that was built on the site was one of the most important early Norman fortifications, controlled the northern approach to London.
