Just four at a time, visitors soon will be allowed access to a long-hidden space inside Florence’s Medici Chapel where delicate charcoal drawings sketched on the walls have been attributed by some experts to Michelangelo.

The secret room – a tiny space just 33ft by 10ft – was discovered in 1975, when officials were searching for a new exit from the Medici Chapel to accommodate increasing visitors.
