A historic society has found itself in a row with Lidl supermarket over plans for a new store which could destroy a civil war monument.
Discount shop giant Lidl has its eye on building a new store in Carmarthen, west Wales.
But plans have been halted by historians who fear a 500-year-old Civil War monument might be under threat from the new supermarket.
Carmarthen Civic Society has objected to the proposals, saying it could affect the nearby Bulwarks monument - built to protect the town in 1651.
A spokesperson said: "We strenuously opposed the application in view of its effect on the Civil War defences on the site known as The Bulwarks, which are a designated Ancient Monument.
"It is particularly disappointing that the proposal pays scant regard to the historical importance of the site and its relevance to the historical landscape of the town.
"The monument and its setting are of interest both to residents of Carmarthen and visitors alike, and the site resonates hugely with those with an interest in the Civil War era.
"Clearly this is a site which has a story to tell, and it should be protected and actively enhanced to enable that story to be told to future generations."
Historic environment service Cadw said: "The monument is of national importance for its potential to enhance our knowledge of later defensive organisation.
"The positioning and design of the supermarket would impact detrimentally on its setting."
Lidl said it took feedback seriously.
A Lidl spokesman said: "Much thought and consideration goes into developing our stores, with our dedicated property team closely evaluating all options available."
"The existing store is not able to meet customers' expectations or accommodate its full range of goods.
"We will work closely with Cadw and the store would be built in line with its planning application."
