Collegium Ragusinum

It is connected to the central Gundulić Square by a monumental stairway known as the Jesuit stairs (Croatian: skale od jezuita, Italian: scalinata dei gesuiti).

[2]: 293  The current complex was then built on plans by Jesuit architect and artist Andrea Pozzo (1642–1709), then renowned for his prior work at the Roman church of Saint Ignatius.

[4] A sculpted plaque dated 1481 showing angels holding a medieval YHS christogram above a Latin inscription,[5] was placed prominently at the base of the staircase leading to the College's entrance.

That name in 1778 replaced the previous inscription Collegium Societatis Iesu at the top of the Jesuit stairs, with the date inscribed there (MDCCLXXV, for 1775 - now partly damaged) left unchanged.

[7] The school was later run by Piarists until 1868, was later a military hospital, then a Catholic seminary, until the creation in 1941 of the current secondary institution, the Diocesan Classical Gymnasium "Ruđer Bošković".
