The most modest of the four palace gates was once the gate to the sea: in Diocletian's day the Adriatic washed right against the southern wall and boats tied up here. Today you step off the Riva through the low arch and stand at once in the vaulted substructures of the palace, which lead up to the Peristyle. Few transitions in Split are as striking: from the bright harbour promenade into cool stone over 1,700 years old.
The central cellar passage to the Riva is free to walk; the side halls need a ticket.
A small next-step selection from the same city.
