Although Twente is the most urbanized part of the province of Overijssel, it is renowned for its scenic countryside. This is sometimes characterized as a bocage landscape, attracting many tourists from other parts of the country, with popular sights such as the Lutterzand on the meandering Dinkel, or the wide heather fields on the Frezenbaarg near Markelo. Twente is bisected from north to south by a range of hills in western Twente (Holterberg, Rijsserberg, Friezenberg, Nijverdalse Berg, Hellendoornse Berg), and hills in the east, with the Tankenberg near Oldenzaal being the highest point. The towns of Ootmarsum, and Oldenzaal to a lesser extent, are known for their scenic historical buildings, the latter of which has a noteworthy Romanesque church called "Oale Grieze" (the ‘Old Grey’), which is the oldest Romanesque church in the Netherlands. Eight Twents towns have obtained city rights: Almelo, Delden, Diepenheim, Enschede, Goor, Oldenzaal, Ootmarsum, and Rijssen.
