If anyone has an interest in Bullfighting , Flamenco and / or Spanish history a real great alternative to the regular tourist route is the massive cemetery of Nuestra Señora de la Almudena . Europe's largest graveyard ( estimated 5 million have been buried here ) . The great torero 'Yiyo' , killed by a bull in the 80s , is there with a statue as well as a famous female bullfighter ( the first woman fighter ) . The legendary flamenco singer Lola Flores has her statue here too next to that of her son Antonio Flores ( rock star ) . Graves of members of the División Azúl are there as well as a fenced of mass grave dedicated to the German Luftwaffe that helped Franco in the Civil War ( complete with swastikas ! ) and many many others . Before the Civil War an estimated 2,500 people were executed against the cemetery walls by firing squad , including the '13 roses' who were a group of women who defended Socialist ideals . There is an office by the side of the massive entrance where you can get a map of the graveyard . If you want to take photos you must get a permit and you are generally told that no names on the headstones should be photographed . Security guards roam around to enforce that but I've never seen anybody caught . It's a very impressive place with nice view over parts of Madrid . It's address is Avenida Daroca 90 .. Metro Elipa .. You could also get off at Metro Ventas by the bullring and take the 20 minute or so walk over the M30 , which is what I used to do . By the way I got approached by 3 women outside the gates who saw me taking photos of the gates themselves ( not a problem ) , but they wanted an assurance from me that I would not take photos inside without permission . I had already done so ( not realising the rules ) , but they can get very forceful about this point .
