Lincoln's Newport Arch restoration work begins
Work has begun to restore a Roman arch in Lincoln city centre.
Newport Arch, which still allows traffic through, formed part of the old city walls and has been damaged by recent cold and wet winters.
The city council has secured a £60,000 grant through Waste Recycling Environmental Limited (WREN) to fund the complicated repair work.
Several damaged stones will be replaced and an extra layer of stones will be laid to protect the top of the arch.
In 2012, it was put on English Heritage's At Risk programme, which has helped attract funding.
Arthur Ward, heritage team leader at the council, said: "The work is vital and we hope the repairs will help secure the arch's future for many more years."
The works on the Third Century Roman north gateway, which was part re-built in the Medieval period, will see a number of damaged stones replaced and a layer of stonework added to the top to act as protection to the Roman brickwork.
The authority described the project as one of the largest since May 1964 when a lorry crash caused extensive damage to the archway.
It is the first in a series of restoration and maintenance projects on the Medieval and Roman walls around the city which will take place over the coming years.
