1. Granada Cathedral, March 2017. The Andalusian city of Granada is globally revered for The Alhambra, a stunning castle-palace perched atop Cerro del Sol (Hill of the Sun). Scores of visitors shuttle in and out just to see the palace, but the city itself is well worth at least a day of your time. Having booked myself into the centrally located hostel Alhambra Zoom, (11 Euros a night!), I eagerly set off into the city to begin my explorations. It wasn’t long before I came upon Granada Cathedral, a hulking beast seemingly crowbarred into its spot in Plaza De Las Pasiegas. It boasts an amazing mishmash of architectural styles, including baroque outside, renaissance inside and gothic roof vaults. There’s a five Euro fee to tour the interior.
