just outside of Medellin is a tourist site which is one of Escobar's old mansions (Hacienda Napoles) and I think where he was set up when in "prison." It has some of his old cars, etc. and even some of the wildlife that he liked back in the day such as hippos.
There's also a nightclub here in Bogota that is the penthouse of a large hotel that I've been to a few times. The place is huge and has a panoramic view of the city and was were Escobar kept his family while on the run from authorities. Must be nice to have had all that money. Hotel Tequendama
