Other excavations done jointly with the 20th Ephorate of Prehistoric and Classical Antiquities near the North Harbour of the city uncovered a multiperiod site with remains extending from a late Ottoman cemetery (including a "vampire" burial, a middle aged man with 20 cms spikes through his neck, middle and ankles) to a substantial Roman building constructed around a colonnaded courtyard (probably a tavern/brothel in its final phase in the mid-4th century AD) to remains of Hellenistic structures and debris from different Hellenistic manufacturing processes (pottery, figurines, cloth making and dyeing, bronze and iron working) to archaic and classical levels with rich collections of Aeolic grey wares.
