The Longos mansion, also known as the Red house due to its red brick exterior, is a three-storey house in Agias Sofias Square in the center of Thessaloniki. It was designed in 1926 by architect Leonardo Gennari for the family of Grigorios Longos, a wealthy textile industrialist from Naousa, in the Neobyzantine style.
He later gave it to his brother, Ioannis, which is why it is known as "Ioannis Longos mansion". In 1983, it was listed by the Greek Ministry of Culture for preservation.Until 1992, there was a cafe called "Ermis" on the ground floor, frequented by retired teachers and professors. Today, in its place, there is a restaurant called "Kourdisto Gourouni". In early 2014, Ivan Savvidis, the wealthy businessman and owner of football team PAOK FC, bought the house for four million euros. A store selling official PAOK merchandise operates there now.
