Task: Question Generation
Input (English): Passage: After the Ashton Canal closed in the 1960s, it was decided to turn the Portland Basin warehouse into a museum. In 1985, the first part of the Heritage Centre and Museum opened on the first floor of the warehouse. The restoration of building was complete in 1999; the museum details Tameside's social, industrial, and political history. The basin next to the warehouse is the point at which the Ashton Canal, the Huddersfield Narrow Canal and the Peak Forest Canal meet. It has been used several times as a filming location for Coronation Street, including a scene where the character Richard Hillman drove into the canal.The earliest parts of Ashton Town Hall, which was the first purpose-built town hall in what is now Tameside, date to 1840 when it was opened. It has classical features such as the Corinthian columns on the entrance facade. Enlarged in 1878, the hall provides areas for administrative purposes and public functions. Meanwhile, the Old Street drill hall was completed in 1887.
There are five parks in the town, three of which have Green Flag Awards. The first park opened in Ashton-under-Lyne was Stamford Park on the border with Stalybridge. The park opened in 1873, following a 17-year campaign by local cotton workers; the land was bought from a local mill-owner for £15,000 (£1.4 million as of 2019) and further land was donated by George Grey, 7th Earl of Stamford. A crowd of between 60,000 and 80,000 turned out to see the Earl of Stamford formally open the new facility on 12 July 1873. It now includes a boating lake, and a memorial to Joseph Rayner Stephens, commissioned by local factory workers to commemorate his work promoting fair wages and improved working conditions. A conservatory was opened in 1907, and Coronation gates installed at both the Ashton-under-Lyne and Stalybridge entrances in 1953.Hartshead Pike is a stone tower on top of Hartshead Hill overlooking Ashton and Oldham. The current building was constructed in 1863 although there has been a building on the site since at least the mid-18th century, although the original purpose is obscure. The pike may have been the site of a beacon in the late 16th century. It has a visitor centre and from the top of the hill it is possible to see the Jodrell Bank Observatory in Cheshire, the Welsh hills, and the Holme Moss transmitter in West Yorkshire.
Output (English): What is the name of the current building that was constructed in 1863, although the original purpose is obscure?
