Taken at the dawn of photography, these unique pictures are some of the first ever taken of the city of Bristol, nearly 100 years before much of its historic centre was destroyed by Nazi bombing. The images, captured between 1850 and 1855 by photographer Hugh Owen, have surfaced after being put up for auction - and could fetch up to £30,000. Everything from the waterfront, city centre and St Mary Redcliffe church can be seen in the shots, as well as The Fourteen Stars Tavern building which was pulled down in 1857. It became part of the site for The Bristol Brewery Georges before that was closed in 1999 and later turned into a block of flats. Many of the buildings pictured have changed dramatically between the 19th century and today, particularly the area of High Street. Other shots are almost identical, including the one of St John's Gate at the Church of St John the Baptist, which shows that little is different in certain areas that escaped the heavy bombing during the Second World War. The albumen prints were made in the 1870s from the original paper negatives of the early 1850s. They are due to go up for auction in Cirencester tomorrow. Stepping back in time: The Fourteen Stars Tavern (pictured left) can be seen in a photo believed to have been taken shortly before it was knocked down. It was replaced by The Bristol Brewery Georges, which has since closed and been converted into flats. As it is today (right) Many uses: There was a builder, undertaker and joiner stationed at Broad Quay Bristol when this photo was taken between 1850 and 1855 . How Broad Quay Bristol looks now. It has become restaurants but retained some of its old character for people to enjoy while they eat . Little difference: The view through St John's Gate at the Church of St John the Baptist has not changed much between 1850 and today - apart from the road works . High Street in Bristol (left in 1850) is one of the areas where the buildings have changed quite dramatically over the past 160 years. The structure was overhauled in 1962 to make way for what is the former Norwich Union building. Today it stands defunct and boarded up (right) This fascinating picture shows Sleep Street in Bristol at the dawn of photography, believed to have been taken between 1850 and 1855 . St Mary Redcliffe church was constructed from the 12th to the 15th centuries and has been a place of Christian worship for over 900 years. Pictured left is what the towering structure looked like in the 19th century after being snapped by Hugh Owen and, right, how it appears now . Hugh Owen's photograph shows St Peter's Hospital, which was destroyed in the Bristol Blitz in 1940. Built as a merchant's house, it had been a showcase of Jacobean architecture before it was bombed . Not much change: The church is renowned for the beauty of its Gothic architecture and is classed as a Grade I listed building by English Heritage. Queen Elizabeth I is said to have described it as 'the fairest, goodliest, and most famous parish church in England' St Mary-Le-Port Street in Bristol. The albumen prints were made in the 1870s from the original paper negatives of the early 1850s . Area of beauty: College Green, Bristol, as it looked in the 19th century. A replica of the Bristol High Cross had been erected there, in the shadow of the cathedral, because the original was deemed too fragile to move again . Missing landmark: The remains of the replica cross can now be seen in nearby Berkeley Square, where they were transferred in about 1950 from College Green (pictured). Much of the trees which shielded the cathedral are now gone . Another image of Sleep Street in Bristol. It is believed the set of pictures could fetch up to £30,000 when they go up for auction tomorrow . This photo shows Host Street in Bristol. It provides a glimpse into the past as much of the historic city centre was destroyed by bombing during the Second World War .
