Some of the most-repeated Vatican "mysteries" turn out to be the easiest to verify.

FACT — a private train station

Vatican City has had its own railway station since 1929, connected to the Italian network by roughly 300 metres of track, used rarely and mostly for freight or ceremonial occasions.

FACT — the Passetto di Borgo

An 800-metre elevated, fortified corridor built in the 13th century genuinely connects the Vatican to Castel Sant'Angelo — popes have used it to flee in emergencies, most famously in 1527.

Misleading name — the "Secret" Archives

Despite the name, "secret" here translates a Latin/Italian sense closer to "private" or "personal" (the pope's own archive) rather than classified. Scholars have been able to apply for access for over a century; the archive was formally renamed the Vatican Apostolic Archive in 2019.

FACT — a supermarket and a pharmacy

With around 800 residents and thousands of daily staff, Vatican City runs its own tax-free supermarket and a well-known pharmacy.
