Mnajdra is a megalithic temple complex built around the fourth millennium BCE; the Megalithic Temples of Malta are among the most ancient religious sites on Earth. In 1992 UNESCO recognized the Mnajdra complex and four other Maltese megalithic structures as UNESCO World Heritage Sites. In 2009 work was completed on a protective tent.
Mnajdra is made of coralline limestone, which is much harder than the soft globigerina limestone of Ħaġar Qim. The main structural systems used in the temples are corbelling with smaller stones, and post-and-lintel construction using large slabs of limestone.
The cloverleaf plan of Mnajdra appears more regular than that of Ħagar Qim, and seems reminiscent of the earlier complex at Ggantija. The prehistoric structure consists of three conjoined but not connected temples: the upper, middle and lower.
The upper temple is the oldest structure in the Mnajdra complex and dates to the Ggantija phase (3600-3200 BC). It is a three-apsed building, the doorway of which is formed by a hole cut into a large piece of limestone set upright, a type of construction typical of other megalithic doorways in Malta. This temple appears originally to have had a vaulted ceiling, but only the base of the ceiling now remain on top of the walls. The pillar-stones were decorated with pitmarks drilled in horizontal rows on the inner surface.
The middle temple was built in the late Tarxien phase (3150 – 2500 BC) and, in fact, is the most recent structure. It is formed of slabs topped by horizontal courses.
The lowest temple, built in the early Tarxien phase, is the most impressive and possibly the best example of Maltese megalithic architecture. It has a large forecourt containing stone benches, an entrance passage covered by horizontal slabs, one of which has survived, and the remains of a possibly domed roof. The temple is decorated with spiral carvings and indentations, and pierced by windows, some into smaller rooms and one onto an arrangement of stones.
The lowest temple is astronomically aligned and thus was probably used as an astronomical observation and/or calendrical site. On the vernal and the autumnal equinox sunlight passes through the main doorway and lights up the major axis. On the solstices sunlight illuminates the edges of megaliths to the left and right of this doorway.References:
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.
