The Brothers of Charity have been involved in the care for people with a mental illness in Belgium since 1815. They were guided by Dr J. Guislain, the first Belgian psychiatrist and doctor-in-chief of the two existing mental hospitals in Ghent. A brand new psychiatric institute began in 1857 and is still working today. Dr J. Guislain Museum was inaugurated within the walls of this institute: it offers a survey of the evolution in the care for people with a mental health illness and highlights the work of Dr J. Guislain and Canon P.J. Triest.
