I visited old Havana and the impressive fortifications of 'el morro' in November 2008. The old city is really impressive and some of the colonial buildings are being restored. One can attend Mass at the main church and the old plazas are a reminder of how important Havana was in the trade with Seville during the Spanish Golden Age. Adding to old Havana's charm is the Caribbean and tropical flair and the strange timewarp presented by all that remains from pre revolutionary Cuba.
