The “V. Papantoniou” Museum has been housed in a restored and suitably modified neoclassical building of the early 20th century, located on 1, V. Alexandrou and Sofroni street, in Nafplio. The first exhibition held in 1974, was dedicated to Peloponnesian rural and urban costumes.

In 1981, it was developed the ground floor to accommodate the exhibition on natural textiles in Greece: production, processing and the application thereof in local clothing and domestic use, as regards arts and crafts, etc., covering the period from 1835 to 1945.
