Fans of Bizet's opera Carmen will want to come here, to see where the famous heroine reputedly rolled cigars on her thighs. At the far end of the Murillo Gardens, opposite Calle San Fernando, stands part of the University of Seville, in what used to be the Real Fábrica de Tabacos (Royal Tobacco Factory). Built in the mid-1700s, the factory employed some 3,000 cigarreras (female cigar makers) less than a century later. Free guided tours (book online only) are available on Tuesdays (11 am, Wednesdays (4 pm), Thursdays (11 am and 4 pm) and Fridays (11 am and 12:30 pm), except in August.
