2006, an international project for a holistic investigation of Pompeiopolis was initiated with extended surveys and goal-oriented excavations. Since 2017 the Kastamonu Museum is carrying out the annual excavations and conservation activities for the touristic development of the site. Although no remains were visible on the surface in 2005, a systematic geophysical survey over Zımbıllı Tepe detected the outline of a large city with roads, public buildings, and two theaters that were successively archaeologically investigated. The excavations in the major theatre unearthed the lowest marble seat rows as well as inscribed architraves with decorated friezes from the scaenae frons. From the inscription, it is understood that at least the stage was built around AD 150. The theatre was dismantled within the 5th century. Scarce remains of an octagonal building were previously identified as the tholos of a macellum, while few Christian graves excavated in 2016 in this area have suggested a later use as a church of the octagonal building. A multiphase Roman domus at the north-eastern foot of Zımbıllı Tepe was first discovered in 1984 by a rescue intervention of the Museum of Kastamonu and reopened in 2006-2008 by the German team. This grand-house occupies a whole block within a network of orthogonal roads that organize the urban plan of this part of the city. The north-eastern blocks were built around the mid-3rd century AD and were progressively deserted since the beginning of the 7th century, with few episodes of partial reoccupation recorded until the 12th century. The grand-house is 2550 square metres wide, its layout is organized around a central peristyle and the northern side is provided by an honour court with direct accesses to wealthy reception rooms decorated with opus sectile wall revetments and mosaic floors. At least four rooms were equipped with a hypocaust heating system. The extensive excavation of the grand-house, still in progress, is accompanied by a systematic conservation program financed by the Meda Foundation, aimed at preserving and developing the monument into a public archaeological area with the involvement of local expertise and stakeholders. It is argued that Pompeiopolis was founded to take over the administrative function of the Hellenistic fortress Pimolisa located in today´s Boyabat which was abandoned and destroyed in the aftermath of the Mithridatic Wars. Although no architectural remains in hitherto excavated areas can yet be assigned to the early phase of the city several coin-finds from this period leave
