The De Bosset Bridge or the De Bosset Causeway is the largest stone bridge on a seawater body and has been in existence since 1813 when the Swiss engineer Charles Philippe De Bosset was employed by the British Army.

Thanks to his contribution in the form of study and construction of the bridge, Monsieur de Bosset was appointed as Governor of Kefalonia from 1810-1814 by the British who reigned the Ionian Islands from 1809-1864.
