Radcliffe Camera
James Gibbs's round Baroque library, built between 1737 and 1748 with money left by the physician John Radcliffe. It is a reading room of the Bodleian Library, so most people see it from Radcliffe Square, but the Bodleian runs a walking tour that goes inside.
Bridge of Sighs
Outdoors
Properly Hertford Bridge, finished in 1914 to a design by Thomas Graham Jackson. It joins the two quadrangles of Hertford College across New College Lane, and gets its nickname from the Bridge of Sighs in Venice, though the college says it looks more like the Rialto.
Tom Tower
Christopher Wren's tower over the main gate of Christ Church, built in 1681 and 1682. The bell inside, Great Tom, rings 101 times every evening at 9.05 pm. Christ Church itself is open to visitors, and a multimedia guide is part of the admission.
Magdalen Tower
Outdoors
A tower 144 feet high, begun in 1492 and finished by 1509, beside Magdalen Bridge at the east end of the High Street. On the morning of 1 May the college choir sings from the top of it to start May Morning.
Ashmolean Museum
The University's museum of art and archaeology, founded in 1683, with collections that run from Egyptian mummies to contemporary art. General admission is free and needs no booking, and its rooftop restaurant serves lunch and afternoon tea.

Covered Market
A market hall between the High Street and Market Street, open since 1774 and owned by Oxford City Council. Independent traders run its shops, cafes and food stalls, and each keeps its own hours.
