DEMOLITION contractors have uncovered Nazi swastikas etched as graffiti by German prisoners of war at a City of London building site.
Orpington firm H Smith Engineers made the discovery while removing Portland Stone from the site of Durrant House, in Chiswell Street.
Workers found the Nazi insignia and prisoners'numbers on the back of the slabs.
Some were etched with a chisel and some drawn in pencil.
They have so far found nearly 30 blocks with swastikas marked on them.
H Smith boss Bill Nickell said: 'We originally thought the building was put up in 1965, but our site foreman spoke to some people locally who said it was built by German PoWs at the end of World War II.
'We've since seen some plans of the building dating from the 1940s, which could corroborate this.
'We thought it was just a typical eightstorey building. I've been in the industry for 40 years and I thought I'd seen it all but I've never come across anything like this before.'
The firm is carrying out the £600,000 demolition package for Kier, which is the main contractor on the Fairplay Estates project.
