Sevillanos built Santa Cruz to survive August. The streets are barely two meters wide, the upper-floor balconies almost touch across them, and bitter-orange trees line every corner that gets direct sun. By 1 PM, walking these alleys feels like 15 degrees cooler than the riverfront half a kilometer away.
The picks below stay inside the old Jewish quarter — Santa María la Blanca to the Cathedral, with the cathedral’s shadow doing the last 60 meters. Don’t take the wider tourist streets unless you have to. Stay Cool will route you off them automatically.
