shores of Storsjön, (English: 'the great lake'), it also has a harbour. There is also a harbour on the Frösö side of the strait. Several bridges span across Storsjön connecting Östersund with communities nearby, Frösöbron across Östersundet, Vallsundsbron from Frösön across Vallsundet to 'the other side' and Rödöbron from Frösön to Rödön in Krokom Municipality. Trade and commerce Like the rest of Jämtland Östersund is heavily dominated by many small businesses. The city is the centre of trade and commerce in Jämtland County and has more than 300 shops. The retail trade's turnover is 30 per cent higher than it ought to be, given the number of inhabitants the city has. Trade in the central business district ( – 'the city') is mostly concentrated on the shopping and pedestrian street Prästgatan where large local shopping malls such as Kärnan and Mittpunkten along with department stores such as Åhléns are located. There are large clothing companies such as H&M and Lindex and smaller ones like WESC, approximately 50 restaurants, shoe stores, sporting goods retailers like Stadium and Intersport, several supermarkets (Östersund has rather few convenience stores), etc. Storgatan, the street that runs parallel with Prästgatan, is also lined with shops, restaurants and coffeehouses. Unlike Prästgatan this street is not a pedestrian street. Östersund is the city in Sweden with the most square metres of window display per capita. The most prominent figure in Östersund's business life throughout the 20th century was the car salesman (who started out selling horses) Sven O. Persson, founder of Persson Invest, Byggelit and Bilbolaget. A significant real estate owner was Maths O. Sundqvist (1950–2012). Östersund has had a long history as a marketplace with the already mentioned ancient Gregorie market, tracing its lineage back to the 11th century, held in early March. Despite being banned in 1914, it continued to be held for a couple of years. In 1950, the market was reborn shortly and was completely resurrected in 1986, when the city celebrated its 200th anniversary, and has been held yearly since then. In 1948, when the markets were non-existent, visions to restore Östersund's market traditions in a modern version were brought up. The result was the trade fair Expo Norr, initiated in 1950 in order to strengthen Östersund as a leading centre of trade in the northern parts of Sweden. The trade fair is an annual event just like Gregorie market, though Expo Norr
