Can Forteza Rey went up on Carrer de Sant Miquel in 1909, and it has been stopping people in their tracks ever since. Coloured mosaics, undulating balconies, dragons, masks and faces that seem to track you from above: it's the kind of building that makes you check whether you've accidentally wandered into a fever dream. The style owes something to Gaudí, but it's distinctly Mallorcan, not a copy of anything from Barcelona.

What makes it stranger still is that for years this fantastical facade housed a dental clinic. Patients waited for their appointments surrounded by fantastical creatures. Perhaps that was intentional. Next door, the former El Águila department store, designed by Gaspar Bennàssar in 1908, completes a rare double act: two buildings that announced Palma's modernist ambitions to the whole street.

VoiceMap's audio tours place Can Forteza Rey within Palma's early-twentieth-century transformation, tracing how a city once defined by Gothic stone decided, almost overnight, to go somewhere wilder.
