San Miguel de Escalada is located 10 km from the Way of St. James pilgrimage route to Santiago de Compostela. The building is an example of Mozarabic art and architecture or Repoblación art and architecture.
An inscription that has disappeared but was published by Father Risco in 1786 gave information about the church's consecration in 951 by Bishop Genadio of Astorga, around the time of the founding of the Kingdom of León. It was constructed on a site dedicated to Saint Michael, probably a Visigothic church.
The monastery church's nave has three aisles separated by columns and large horseshoe arches, with their apses and a crossing, which is not covered by a cimborio or central tower. The choir is separated from the principal nave by three horseshoe arches sometimes called an iconostasis).
Despite the floor plan, the building appears from the exterior as a rectangular block. All arches take down in marble shafts and Corinthian steeples proceeding from other Visigothic or Roman constructions (as it may be appreciated in a cyma carved as from a gravestone, perhaps from the nearby Roman city of Lancia).
The building has wood panels, which are decorated with paintings from the 15th century.
Architectural highlights include a meridional porch fixed by twelve horseshoe arche), which were built in two different phases: the seven occidental arches, with columns and steeples are in the moorish style, while the Mozarabic work from the 10th century is preserved in the alfiz decorations around the arches.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.
