The Old Quarter of Salamanca is the historic heart of Salamanca, Spain, and a World Heritage site. Renowned for its rich concentration of Plateresque architecture, the district is centered around the Plaza Mayor — one of the most magnificent public squares in Europe — and the towering New Cathedral and Old Cathedral. This ancient center is home to the University of Salamanca, founded in 1218, which is the oldest university in the Hispanic world and one of the oldest in the West. Walking through its narrow streets, visitors encounter the House of Shells and the Roman Bridge that spans the Tormes River, all crafted from the characteristic golden stone that gives the city its nickname as the Golden City. - AsNotedIn
