Oxford is a city, and the county town of Oxfordshire, in South East England. The city, made prominent by its medieval university, has a population of just under 165,000, with 151,000 living within the district boundary. The rivers Cherwell and Thames run through Oxford and meet south of the city centre. For a distance of some 10 miles (16 km) along the river, in the vicinity of Oxford, the Thames is known as The Isis.
Buildings in Oxford demonstrate an example of every British architectural period since the arrival of the Saxons, including the iconic, mid-18th century Radcliffe Camera. Oxford is known as the "city of dreaming spires", a term coined by poet Matthew Arnold in reference to the harmonious architecture of Oxford's university buildings. The University of Oxford is the oldest university in the English-speaking world.
