Agias Sofias Square

The Longos Mansion (Greek: Μέγαρο Λόγγου), also known as the Red House (Κόκκινο Σπίτι) 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.The company that undertook its construction went bankrupt a few months later and Longos' factory in Naousa was destroyed by a fire. As a result, rumors were created about suicides and ghosts in the abandoned mansion.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" (meaning Clockwork Pig). 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.

Aghia Sofia (Greek: Αγία Σοφία, literally Holy Wisdom) is an under-construction metro station serving Thessaloniki Metro's Line 1 and Line 2. The station is named after the church of Hagia Sophia, located nearby. It is expected to enter service in 2023 Construction of this station has been held back by major archaeological finds, and it is designated as a high-importance archaeological site by Attiko Metro, the company overseeing its construction. Here, as well as at Venizelou, Roman Thessaloniki's marble-clad and column-lined Decumanus Maximus (main east–west avenue), along with shops and houses, was found running along the route of the Via Egnatia (modern Egnatia Street) at 5.4 metres (18 ft) below ground level. Additionally, a public square was also found at this station. The discovery was so major that it delayed the entire Metro project for years. A historian dubbed the discovery "the Byzantine Pompeii". Aghia Sofia station will feature a mini museum within the station, similar to those of Athens Metro stations like Syntagma, which houses the Syntagma Metro Station Archaeological Collection. Unlike Venizelou, however, the archaeological finds will not be kept in situ; they will be disassembled and reassembled elsewhere. The station also appears in the 1988 Thessaloniki Metro proposal.
