came up to me and corrected me. ‘The site at the airport is a special holding facility, not a detention centre. We should be careful with the terms.’ Irrespective of the official term used to describe a facility, their essence as spaces, run by the police, where migrants are deprived of their freedom, usually in detrimental conditions, with ill-treatment by the authorities prevailing, remains common among them. By using the term immigration detention throughout the thesis, I refer to the complex, often hidden and remote, formal and informal carceral infrastructure that the Greek nation state has developed to restrict mobility across its national borders and to regulate the presence of foreigners within its territory (Loyd and Mountz, 2018). Arguably, the term is quite expansive. The blurred boundaries between reception and detention centres have been widely documented, with de facto detention during reception and identification procedures at the borders being the norm, rather than an exception (Asylum Information Database, 2021; Majcher, 2018; Matevžič, 2019). In this context, the term immigration detention could include these facilities. However, I have decided not to include them in my analysis because these sites have been over-researched. In doing so, I aim to move the understanding of detention past the spectacle at the border to the interior of the state (Mainwaring and Silverman, 2017, p. 28). 20
