- 51 3. Disciplinary detention facilities 119. At the time of the visit, the disciplinary detention facility at the Infantry Cadet Officer Academy in Heraklion, consisting of 3.6 m² cells, was being used for storage. The CPT wishes to make clear that, in view of their size, the facility's cells are not suitable for overnight detention. The cells in the disciplinary unit of the 15th Brigade of the Army in Kastoria were somewhat larger (5.5 m²); however, they had very limited access to natural light and poor artificial lighting. The cells were furnished with beds, had been painted recently and were in a reasonable state of cleanliness. In view of the delegation's findings, the CPT welcomes the fact that disciplinary sanctions for military personnel were in practice being limited to confinement to dormitory or barracks, and that neither of the two detention facilities visited had been used for detention purposes for some considerable time.
