Follow the baroque stairs, built in the image of the Spanish ones, to the Boškovićeva poljana. This stately edifice, envisioned in 1738 by a roman architect Pietro Passalacqua, draws the attention of people from around the world. Jesuits' Staircase reflects the modern attitude to and interpretation of the architecture and urban planning consciously for that part of the Old Town that was also meant to emphasize the prominent position of the Jesuit college and church. It is a paragon of architecture and construction that leaves no one indifferent. These steps lead to Gundulićeva poljana or Boškovićeva poljana, and thus to the Restaurant & Bar Ruđer.
Church of St. Ignatius, or Jezuite as it is reffered to in Dubrovnik, is devoted to St. Ignatius de Loyola who founded the Jesuit (the Society of Jesus) religious order. The church itself has been built according to the plans made by a Jesuit painter and architect, Andrea Pozzo. The front of the church dominates the Boškovićeva poljana (square). Alongside it, it is essential to higlight the frescoes on the vault painted by the Sicilian master of Spanish origin, Gaetano Garzia. Because of its acoustic features, the church serves as one of the most exclusive concert venues in the city.
