Helsingør’s well-preserved medieval quarter is dominated by Stengade, the main shopping street, which is linked by a number of narrow alleyways to Axeltorv, the town’s small market square and– a nice place to enjoy a beer. Near the corner of Stengade and Skt. Annagade is Helsingør’s cathedral, Skt. Olai Kirke (Mon–Sat: May–Aug 10am–4pm; Sept–April 10am–2pm; free), while beyond is Skt. Mariæ Kirke (mid-May to mid-Sept Tues–Sun 10am–3pm, mid-Sept to mid-May Tues–Sun 10am–2pm, free; guided tours at 2pm Mon–Fri; 20kr), whose Karmeliterklostret, built circa 1400, is now the best-preserved medieval monastery in Scandinavia (guided tours only; arrange via the church office). Its former hospital now contains the Town Museum (Tues–Sun noon–4pm, Sat till 2pm; 20kr), which displays an unnerving selection of surgical tools used in early brain operations.
