Visit the seat of state government on the north side of Plaza Grande. You can see Fernando Castro Pacheco's murals of the bloody history of the conquest of the peninsula, painted in bold colors and influenced by the Mexican muralists José Clemente Orozco and David Alfaro Siquieros. On the main balcony (visible from outside on the plaza) stands a reproduction of the Bell of Dolores Hidalgo, on which Mexican independence rang out on the night of September 15, 1810, in the town of Dolores Hidalgo in Guanajuato. On the anniversary of the event, the governor rings the bell to commemorate the occasion. There's a branch of the state tourist office on the ground floor.
