public. Three principal phases were identified: 1860s original; 1870s updates and adaptions; 1887–90 redecoration, which returned the main spaces to the original green colours and motifs created by Crace. Once lantern repairs were complete, the Trust replaced the elderly chenille carpet destroyed by contractors working for Christie's with a new Wilton carpet with a replica design by Linney Cooper, bought with £45,000 from public lottery donations. Contents Christie's originally estimated the house contents at in excess of 10,000 items, but by 2008 a total of 30,000 items had been listed including: William Butterfield designed silver; original print books by Pugin and Ruskin; an unexploded Second World War bomb; a jewel-encrusted chalice; a roll of 19th-century flock wallpaper; and a coconut with carved face and hair. By 2013 the inventory had risen to 47,154 items, with still more rooms to unpack and catalog. Paintings Many of the family's extensive collection of paintings, most sourced from Spain by William, were donated to the Trust. In part this was due to their poor condition, which involved not just water but also ironically guano damage. The most important painting in the collection is the 17th-century work by Zambrano of St Lawrence, which hangs in the middle of one of the walls of the hall. It was cleaned and repaired by local art conservators Bush and Berry, who are based in a chapel William Gibbs built in the village of Flax Bourton. In 2011 the Trust bought the painting The Mater Dolorosa (Mother of Sorrows) by Bartolomé Esteban Murillo at Christie's auction in New York, which had hung at Tyntesfield since William purchased it until some time after 1910. Home Farm Visitor Centre The Home Farm buildings were built in the 1880s, split over two levels. To the south is a two-storey covered yard with a timber roof structure, used for the rearing of farm animals. On the upper level is the main yard, where to the east and west are two wings, one side of which housed the former piggery. The farm offices make up the north wing, to fully enclose the square but gently south-sloping yard. The Grade II* listed buildings needed full renovation, which took a secondary priority in the Trust's plans after the house. The Trust have converted the buildings into an integrated and self-contained visitor centre, which opened in mid-2011 with: Upper yard: Ticket and information office Demonstration area: country
