New input: Article: Great Yarmouth is an English seaside town situated at the mouth of the River Yare, about 120 miles to the northeast of London. Around 5 million people visit Great Yarmouth every year, making it one of Britain's most popular seaside resorts. Formerly the home of one of the most profitable fishing industries, Great Yarmouth is a busy and very popular seaside resort. Undoubtedly, one of the most popular attractions is Great Yarmouth Pleasure Beach, a historic free entry pleasure park, which draws annually 1.5 million visitors. The two piers , Britannia Pier and Wellington Pier, both contain family-orientated entertainment. As well as the usual thrills one would expect on a classic British seafront, Great Yarmouth also has a quieter side, with a fascinating heritage quarter to explore. Not many people know that Great Yarmouth has the most complete city walls after York, with heritage walks to help you discover this medieval attraction along with several museums and houses dating back to many centuries. If ghost walks are more your cup of tea, Eerie Tales and Yarmouth Yarns is the tour for you. Great Yarmouth is also a centre for the North Sea oil and gas industry and increasingly for offshore wind power. The Great Yarmouth Outer Harbour is a huge development currently taking place which can see larger ships coming to the town. The Great Yarmouth Maritime Festival in September each year celebrates Great Yarmouth's maritime heritage. Over the past few years, Great Yarmouth has seen significant construction spending to improve and modernize the popular seafront area and to ensure it is linked to the town centre. Regent Road has a brilliant ceiling of light which is lit up in the evenings and is now a lovely street leading from the town centre to the seafront area.
