Inside the construction site of the new farmers market (inexcusably built on the New Fortess western ditch) was found some ruins of an old building dated from the period of the british occupation of Corfu (1812-1864). Its use most probably was a defensive one. It might have served as mews, as an arsenal or even as a watchman's house.
Anyway, an extensive and systematic archeological survey should be done in order to assess and decide whether this finding should be protected or be buried and swallowed by the new farmers market. Unfortunately, the evaluation is going very slow and the market has been under construction for some 3 or 4 years now (it should have been constructed in under a half year's period!).
In my opinion, the farmer market should never have been constructed on that historic site. Being on the venetian 16th century ditch, it should have been preserved and reconstructed in its former state, showing off to locals and greeks alike the extensive and unique defensive system that Corfu had in the past.
