Ellesmere is a market community near Oswestry in north Shropshire, England, significant for its proximity to a number of famous Meres. The town is situated by the side of Ellesmere (also known as 'the Mere'), among the largest natural meres in England outside the Lake District as well as among nine glacial meres in the area. ('glacial' suggests that the clinical depression inhabited by the mere was the place of a block of ice that continued at the end of the last Glacial epoch). These meres are various from those in the Lake District in that they do not have a circulation of water into them to preserve the level. A man-made island in the Mere was constructed in 1812 from dirt removed during the production of the gardens at Ellesmere House. This was later on called Moscow Island, as Napoleon was compelled to pull back from Moscow that year. The Mere has a site visitors' centre as well as is prominent with birdwatchers, most of whom check out to see grey herons nesting. There are 8 other meres close by: Blakemere, Colemere, Crosemere, Kettlemere, Newtonmere, Whitemere, Sweatmere and also Hanmer Mere. The civil church which makes up the community is Ellesmere Urban; the bordering parish, covering a big rural area, is Ellesmere Rural.
