Small circular monument (rotunda) on the Spianada, in the type of a circular monopteral Ionic temple, built in honour of the first High Commissioner of Corfu, Sir Thomas Maitland. It was the work of the British military engineer G. Whitmore, executed in Maltese stone, with sculptural decoration by the Corfiot sculptor Prosalendis. Built above a cistern of Venetian date, it continued for a time to fulfil this utilitarian function.
