This sunny sandstone city boasts Spain's grandest plaza, its oldest university, and a fascinating history, all swaddled in a strolling, college-town ambience. Salamanca — a youthful and untouristy Toledo — is a series of monuments and clusters of cloisters. The many students help keep prices down. Take a paseo with the local crowd down Calle de Rúa Mayor and through Plaza Mayor. The young people congregate until late in the night, chanting and cheering, talking and singing. When I asked a local woman why young men all alone on Plaza Mayor suddenly break into song, she said, "Doesn't it happen where you live?"
