text: Some of the oldest surviving photographs of the Houses of Parliament and Windsor Castle, dating back more than 150 years, have been found. The remarkable images were shot by photographer Victor Albert Prout, who developed the negatives in an improvised dark room on board his punt which he sailed along the River Thames. And despite being more than 150 years old, most of the images capturing the iconic landmarks along the river are instantly recognisable today. Scroll down for video . Prout travelled along the River Thames in a makeshift boat where he installed a dark room (centre, front), capturing and developing his images on site, like this one of Windsor Castle (top right) Prout's collection is the oldest documented record of Britain's best known landmarks, such as Windsor Castle, seen from the banks today . A photo of taken of Richmond Bridge shows the familiar arches of the 18th century stonework, clearly recognisable today. While a picture taken from the banks of the Thames of Windsor Castle, showing Prout's floating dark room in the foreground, is remarkably similar to contemporary pictures of the iconic building. Another shows the Houses of Parliament in the 1850s when Henry John Temple The Viscount Palmerston was Prime Minister, and is strikingly similar to photos taken today. The pictures are to be sold as a collection at the Oxford Book Fair and are estimated to sell for around £30,000. Prout travelled around the Thames on his boat to capture images of the well known landmarks, developing them on the spot His floating dark room construction is often seen tethered to a skiff in some of the photographs. As an artist and photographer was renowned for his panoramic pictures, captured along the stretch of the River Thames - featuring images from the Houses of Parliament to Magdalen Bridge in Oxford. He was commissioned to take the collection of pictures for The Book of the Thames: From Its Rise to its Fall, by Mr and Mrs S.G. Hall. The photographer was known for his panoramic images, such as this one taken overlooking the River Thames, of Richmond Bridge . Richmond Bridge today is busier than the scene surrounding the 18th century stone bridge captured by Prout around 150 years ago . The buildings and riverside of Marlow was captured in a photograph taken by Prout, who then developed his pictures as quickly as he could . Today's picture of Marlow - with the church spire dominating - bears a striking resemblance to that taken by Proust, more than 150 years ago . The images, such as this of Iffley Mill, were saved by Prout in his book of pictures of the Thames in the mid 1850s and will now be auctioned . Some of the photos capture how the areas have changed, such as at Iffley where the watermill no longer stands after it was burned to the ground in 1908, having survived for almost 800 years . Prout's photography along the River Thames included this shot of Twickenham in the 1950s, with his darkroom boat in the foreground (right) Twickenham has been significantly developed since the 1850s when Prout captured his image of the London suburb along the Thames . The photos - believed to be the the first documented collection of the UK's greatest river - were eventually published by Prout's father's publishing company, Virtue and Co, in around 1862. Only a handful of copies of the photographs are known to exist, with most in specialist collections. The last to appear at auction was at Sothebys in 1981. Each of the photographs captured a historical record of the area at the time -  with some also showing how changes have occurred in the last 150 years. At Iffley, a watermill built during the 12th century, was a focal part of Prout's image. But in photos from today the mill is absent - after it was burned to the ground in the early 1900s. Prout's image provides a historical record of the construct, which produced malt, barley and corn for almost 800 years. But most of the photos show how little things have changed - such as the photos of the Houses of Parliament and Marlow Lock. An image of the Houses of Parliament and Westminster Bridge, taken by Victor Albert Prout, is believed to be one of the oldest photographs . Prout's picture of the Houses of Parliament is thought to be the oldest surviving image of the landmark, which looks similar today . A black and white photograph of Hampton Court features in Prout's groundbreaking photo album of panoramic views of the River Thames . Hampton Court is in full view overlooking the River Thames in an image taken from the exact same spot today as the one several years ago . The images capture how London's landmarks appeared in the nineteenth century, such as at Great Marlow Lock, as he travelled past . Marlow lock and weir lies on the River Thames today after being built in 1773 and captured by Prout almost 100 years later . The collection will be sold by Antiquates Ltd - Fine and Rare Books, at the Oxford book fair, held on April 25 and 26, for £28,500. Last month an image taken by Prout of young men playing cricket at Eton was discovered and at 150 years old, was believed to be the earliest ever photograph of a school cricket match, and the second oldest of any cricket anywhere. The image, which showed men playing in waistcoats, was signed in pencil by Prout and taken just five years after the first ever image illustrating the sport. This was captured by Roger Fenton in 1857, a founding member of the Royal Photographic Society and famous for his photographs of the Crimean War. Prout's photo captures the calmness at Wallingford Bridge - which connected Wallingford with Crowmarsh Gifford in Oxfordshire . Today Wallingford Bridge is still a calm stretch of waterway on the River Thames, with most traffic now crossing Winterbrook Bridge instead . Snapshots in the collection, including this of barges in Oxford, will be sold when it is sold at the Oxford Book Fair for around £30,000 . The busy waterways in Oxford, pictured in 2009, bear a striking resemblance to the bustling river captured by Prout 150 years earlier . The incredibly rare collection of photographs taken from London to Oxford is to be sold and has an estimated value of about £30,000 .
