The Nerantzopoulos (or Hatziyiannidis) mansion is situated on Hora's main square. According to the inscription on the facade, it was built in 1754 by Hatziyiannidis who was a merchant in Budapest (Nerantzopoulos acquired the house later).
Its decoration and plaster-framed transoms are impressive. From the wooden ceiling in the 'iliakos' (the main room) on the mezzanine hang sculptures of a melon and a sliced watermelon. In the transoms, apart from their lovely plaster frames, of interest are the incised designs, inscriptions and lines of verse. Artfully written on smoked glass, the verses are composed in an old fashioned language and praise the beauty and magnificence of the house.
