The Isle of Boúrdzi was fortified in 1471 by the Venetians in order to protect the harbour entrance and was reinforced in the early 18C; the chief defence is a strong polygonal tower topped by a gun platform. During the last century, the public executioner of Náfplio lived on the island. It is currently a posh hotel. View of the city and its two citadels, Akronafplía and Palamídi.
