<P0-S0> The building is named after Gilbert Sheldon, chancellor of the University at the time and the project's main financial backer. <P0-S1> The Sheldonian Theatre, located in Oxford, England, was built from 1664 to 1669 after a design by Christopher Wren for the University of Oxford. <P0-S2> It is used for music concerts, lectures and University ceremonies, but not for drama until 2015 when the Christ Church Dramatic Society staged a production of "The Crucible" by Arthur Miller. <SEP> <P1-S0> English Heritage is a governmental body with a broad remit of managing the historic sites, artefacts and environments of England. <P1-S1> 17 of the 25 United Kingdom UNESCO World Heritage Sites fall within England. <P1-S2> It is currently sponsored by the Department for Culture, Media and Sport. <P1-S3> The charity National Trust for Places of Historic Interest or Natural Beauty holds a contrasting role. <P1-S4> Some of the best-known of these are: Hadrian's Wall, Stonehenge, Avebury and Associated Sites, Tower of London, Jurassic Coast, Saltaire, Ironbridge Gorge, Studley Royal Park and various others.There are many museums in England, but perhaps the most notable is London's British Museum. <P1-S5> Its collection of more than seven million objects is one of the largest and most comprehensive in the world, sourced from every continent, illustrating and documenting the story of human culture from its beginning to the present. <P1-S6> The British Library in London is the national library and is one of the world's largest research libraries, holding over 150 million items in all known languages and formats; including around 25 million books. <P1-S7> The most senior art gallery is the National Gallery in Trafalgar Square, which houses a collection of over 2,300 paintings dating from the mid-13th century to 1900. <P1-S8> The Tate galleries house the national collections of British and international modern art; they also host the famously controversial Turner Prize. <SEP> <P2-S0> The small brick church is of an unusual design in London, being based on that of a Greek cross; it utilises a vaulted square within a square, a formula based on the Nieuwe Kerk in Haarlem in the Netherlands. <P2-S1> Wren also used a similar design at St Martin Ludgate and St Mary-at-Hill. <P2-S2> St Anne and St Agnes was rebuilt by Sir Christopher Wren in 1680, with possible contributions from Robert Hooke. <P2-S3> The parish was united with the parish of St John Zachary by Act of Parliament in 1670 as St John's was not rebuilt after the Great Fire. <SEP> <P3-S0> somapura mahavihara (bengali: সোমপুর মহাবিহার shompur môhabihar) in paharpur, badalgachhi upazila, naogaon district, bangladesh is among the best known buddhist viharas in the indian subcontinent and is one of the most important archaeological sites in the country. <P3-S1> it was designated as a unesco world heritage site in 1985. it dates from a similar time period to the nearby halud vihara and to the sitakot vihara in nawabganj upazila of dinajpur district. <SEP> <P4-S0> st helena has long been known for its high proportion of endemic birds and vascular plants. <P4-S1> the highland areas contain most of the 400 endemic species recognised to date. <P4-S2> much of the island has been identified by birdlife international as being important for bird conservation, especially the endemic saint helena plover or wirebird, and for seabirds breeding on the offshore islets and stacks, in the north-east and the south-west important bird areas. <P4-S3> on the basis of these endemics and an exceptional range of habitats, saint helena is on the united kingdom's tentative list for future unesco world heritage sites.
