New signs are being installed to mark the boundaries of the historic Yorkshire Ridings.
The North, East and West Ridings were abolished in 1974, with some areas becoming part of neighbouring counties.
The Yorkshire Ridings Society and the Historic Counties Trust, supported by North Yorkshire Council, marked Yorkshire Day today with the installation of new road signs marking the boundaries of the three ridings.
The new signs were announced in April to mark 50 years since the enactment of the Local Government Act 1972.
As a result the Ridings County Councils were abolished along with many other local authorities across the country.
However, campaigners have argued that the Act was meant to change the pattern of local government, not alter counties as cultural, geographic and historic places.
Nigel Wilkin of the Yorkshire Ridings Society, said: 'If we don't make this effort we run the risk that the history, heritage and cultural identity of these areas will disappear.
'We are trying to promote and explain to people that the ridings haven't gone away.'
