The triangular main plaza of central Guanajuato, planted with manicured Indian laurel trees clipped into a flat green canopy and ringed with cafés. Mariachi bands play in the bandstand most evenings; estudiantinas — student musicians in seventeenth-century costume — gather here at 8 pm before leading singing walks through the alleys. The plaza is the natural starting point and meeting point for anything you do in the city.
