 Another development of Matviyenko's governorship was tourism; by 2010 the number of tourists in Saint Petersburg doubled and reached 5.2 million, which placed the city among the top five tourist centers in Europe.Some actions and practices of Governor Matviyenko have drawn significant criticisms from the Saint Petersburg public, the media, and opposition groups.In particular, new construction in already heavily built-up areas and several building projects were deemed to conflict with the classical architecture of the city, where the entire centre is a UNESCO World Heritage site.
