A famous viewpoint at the top of Richmond Hill, the only in the country protected by an Act of Parliament has been neglected, critics said.
The pavement and railings above Terrace Walk are in a state of disrepair, despite several complaints.
Thousands of visitors from all over the world come to see the famous view from Richmond Hill, but the railings are leaning to one side and the pavement uneven.
Richmond Council spent £1.5m on York stone pavements in Whitton High Street and York Street, Twickenham.
Councillor David Williams, ward member for Ham, Petersham and Richmond Riverside, said: “If the Tories think they can spend an extra £1m on York stone pavements, why is there still crumbling uneven tarmac with wonky railings above Terrace Walk?
“Don’t they have any pride in the famous view from Richmond Hill, protected by an Act of Parliament?”
The council said the walkway was in line for repair and work would start by June, but the improvements were not part of a wider regeneration project.
Councillor Pamela Fleming, cabinet member for environment, said: “We have plans to repair it and straighten the railings.
“It is a very important heritage site but I think Coun Williams needs to remember the Lib Dems were in power for a long time and he did not take any action to deal with it then.
“In terms of Twickenham and Whitton, they are heritage sites as well.
“We do, of course, have pride in Richmond Hill and we have done an enormous amount to regenerate the borough in recent years.”
