were chosen for the sailing events in the 2012 Summer Olympic Games, the area underwent an increased investment in infrastructure and a growth in the marine leisure sector. It is expected that this will continue to have a positive effect on local businesses and tourism. Tourism has grown in Dorset since the late 18th century and is now the predominant industry. It is estimated that 37,500 people work in Dorset's tourism sector. Some 3.2 million British and 326,000 foreign tourists visited the county in 2008, staying a total of 15.1 million nights. In addition there were 14.6 million day visitors. The combined spending of both groups was £1,458 million. Towns received 56% of Dorset's day trippers, 27% went to the coast and 17% to the countryside. A survey carried out in 1997 concluded that the primary reason tourists were drawn to Dorset was the attractiveness of the county's coast and countryside. Numbers of domestic and foreign tourists have fluctuated in recent years due to various factors including security and economic downturn, a trend reflected throughout the UK. Manufacturing industry in Dorset provided 10.3% of employment in 2008. This was slightly above the average for Great Britain but below that of the South West region which was at 10.7% for that period. The sector is the county's fourth largest employer, but a predicted decline suggests there will be 10,200 fewer jobs in manufacturing by 2026. Culture As a largely rural county, Dorset has fewer major cultural institutions than larger or more densely populated areas. Major venues for concerts and theatre include Poole's Lighthouse arts centre, Bournemouth's BIC, Pavilion Theatre and O2 Academy, and the Pavilion theatre in Weymouth. One of Dorset's most noted cultural institutions is the Bournemouth Symphony Orchestra which was founded in 1893. Based in Poole, the orchestra performs over 130 concerts across southern England each year. Dorset has more than 30 general and specialist museums. The Dorset County Museum in Dorchester was founded in 1846 and contains an extensive collection of exhibits covering the county's history and environment. The Tank Museum at Bovington contains more than 300 tanks and armoured vehicles from 30 nations. The museum is the largest in Dorset and its collection has been designated of national importance. Other museums which reflect the cultural heritage of the county include The Keep Military Museum in Dorchester, the Russell-Cotes Museum in Bournemouth, the Charmouth Heritage Coast Centre, Poole
