About Borgo Maggiore

Borgo Maggiore is more than a parking point beneath the capital. Its Piazza Grande hosts a market tradition documented since the thirteenth century, while the surrounding streets, churches, and lower slopes show a more everyday side of San Marino. The cable car climbs roughly 200 metres to the historic center in under two minutes, making the two places easy to combine. April through October is the broadest walking window, excluding August from the recommended set to favor slightly cooler and less pressured days.
