Cactus Gardena Cartagena

We have moved 60 miles or so down the coast to Cartagena, one of several  Carthagenas around the world, and with a name essentially meaning 'new Carthage',  just like new York. 
We arrived latish in the day so had no time to explore the town properly; these cacti were in a garden by the park where we walked with the Krays.
