Fort Lovrijenac or St. Lawrence Fortress is located outside the western wall of the city of Dubrovnik. Famous for its plays and importance in resisting Venetian rule, it overshadows the two entrances to the city, from the sea and by land. Early in the 11th century the Venetians attempted to build a fort on the same spot where Fort Lovrijenac currently stands. If they had succeeded, they would have kept Dubrovnik under their power, but the people of the city beat them to it. The 'Chronicles of Ragusa' reveal how the fort was built within just three months time and from then on constantly reconstructed. When the Venetian ships arrived, full of materials for the construction of the fort, they were told to return to Venice.
Lovrijenac has a triangular shape with three terraces. The thickness of the walls facing the outside reach 12 metres whereas the section of the walls facing the inside, the actual city, are only 60 centimetres thick. Two drawbridges lead to the fort and above the gate there is an inscription Non Bene Pro Toto Libertas Venditur Auro ('Freedom is not to be sold for all the treasures in the world'). Lovrijenac's use as a stage was a recent addition to the history of the fort, and the performance of Shakespeare's 'Hamlet' has become the symbol of Dubrovnik Summer Festival.
The Palazzo Colonna is a palatial block of buildings built in part over ruins of an old Roman Serapeum, and has belonged to the prestigious Colonna family for over twenty generations.
The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante in his visit to Rome. The first documentary mention notes that the property hosted Cardinal Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Martin V (1417–1431).
With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of pope Julius II. The Colonna"s alliance to the Habsburg power, likely protected the palace from looting during the Sack of Rome (1527).
Starting with Filippo Colonna (1578–1639) many changes have refurbished and create a unitary complex around a central garden. Architects including Girolamo Rainaldi and Paolo Marucelli labored on specific projects. Only in the 17th and 18th centuries were the main facades completed. Much of this design was completed by Antonio del Grande (including the grand gallery), and Girolamo Fontana (decoration of gallery). In the 18th century, the long low facade designed by Nicola Michetti with later additions by Paolo Posi with taller corner blocks (facing Piazza Apostoli) was constructed recalls earlier structures resembling a fortification.
The main gallery (completed 1703) and the masterful Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew the Connestabile Lorenzo Onofrio Colonna and includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci (painting of The Beaneater), Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571). The gallery is open to the public on Saturday mornings.
The older wing of the complex known as the Princess Isabelle"s apartments, but once housing Martin V"s library and palace, contains frescoes by Pinturicchio, Antonio Tempesta, Crescenzio Onofri, Giacinto Gimignani, and Carlo Cesi. It contains a collection of landscapes and genre scenes by painters like Gaspard Dughet, Caspar Van Wittel (Vanvitelli), and Jan Brueghel the Elder.
Along with the possessions of the Doria-Pamphilij and Pallavacini-Rospigliosi families, this is one of the largest private art collections in Rome.
