Museo de Arte Contemporáneo Querétaro (MACQ)
Although less visited than some of the city's better-known attractions, this excellent (and free) art museum shows thoughtful and well-curated rotating exhibits of contemporary art. It's on a hilltop in the attractive La Cruz neighborhood, in a beautiful historic building beside the imposing Santuario de la Santa Cruz de Los Milagros. There are two floors of galleries, and the art is by a mix of regional and international artists.
