National Gallery – Nafplio Annex

This arm of the Athens National Gallery is housed in a stunningly restored neoclassical building (don't be deterred; the front door looks to be closed). It features numerous seascapes and different thematic takes on the 1821 Greek War of Independence, including paintings by Theodoros Vryzakis and Dionysios Tsokos, who are considered the most important Greek artists of the postwar years. Entry is free on Mondays.
