According to Bulgarian Helsinki Committee, "The SAR Pastrogor transit centre, situated on the Bulgarian-Turkish border can also be used as a closed facility, if necessary. Since the beginning of its operation in May 2012, it has been operating as an open facility. However, on 19 December 2025 SAR handed back to Migration Directorate-MOI the closed reception ward in Busmantsi detention centre and transferred asylum seekers detained pending their procedure for international protection to Pastrogor transit centre, thus designating it to serve as a closed reception center (ЦЗТ) with a capacity of 300 places."
