Smithills Hall was where, in 1555, George Marsh was tried for heresy during the Marian Persecutions. After being "examined" at Smithills, according to local tradition, George Marsh stamped his foot so hard to re-affirm his faith, that a footprint was left in the stone floor. It is a Grade I listed building and is now a museum. Hall i' th' Wood, now a museum, is a late mediaeval yeoman farmer's house built by Laurence Brownlow. Around 1637 it was owned by the Norris family, who added the stone west wing. In the 18th century it was divided up into tenements. Samuel Crompton lived and worked there. In the 19th century it deteriorated further until in 1895 it was bought by industrialist William Hesketh Lever, who restored it and presented it to Bolton Council in 1900. Bolton's 26 conservation areas contain 700 listed buildings, many of which are in the town centre, and there is parkland including the Victorian Queen's Park, Leverhulme Park and other open spaces in the surrounding area. These include Le Mans Crescent, Ye Olde Man & Scythe, Little Bolton Town Hall, the Market Place, Wood Street and Holy Trinity Church. The Market Hall of 1854 is a Grade II listed building. Outside the town centre can be found Mere Hall, Firwood Fold, Haulgh Hall, Park Cottage, St Mary's Church, Deane, Lostock Hall Gatehouse and All Souls Church. Notable mills still overlooking parts of the town are Sir John Holden's Mill and Swan Lane Mills. Most views northwards are dominated by Rivington Pike and the Winter Hill TV Mast on the West Pennine Moors above the town. Bolton is well served by the local road network and national routes. The A6, a major north–south trunk road, passes to the west through Hunger Hill and Westhoughton. The A666 dual carriageway, sometimes referred to as the Devil's Highway because of its numeric designation, is a spur from the M61/M60 motorway interchange through the town centre to Astley Bridge, Egerton, Darwen and Blackburn. The M61 has three dedicated junctions serving the borough. A network of local buses coordinated by Transport for Greater Manchester serves the Bolton district and beyond; bus operators include Arriva North West and Diamond North West. Bolton is also served by the National Express coach network. The bus station on Moor Lane was scheduled to be replaced by a new interchange in the town centre next to the railway station by the end of 2014, at a cost of £48 million.
