About San Marino City

Città di San Marino is compact but steep, with the Palazzo Pubblico, Basilica of Saint Marinus, museums, defensive walls, and the towers of Mount Titano arranged across different levels. Walking between the towers adds the landscape and Adriatic views that a quick stop in the central shops misses. April through October is the broadest season for exploring on foot, with August excluded from the recommended set to favor less intense heat and pressure. Park below the old town or use the cable car from Borgo Maggiore, then wear shoes suited to polished stone and inclines.
