St Mary’s Cathedral was originally established by Danes on 13th century and it is the oldest church in Tallinn and mainland Estonia. It is also the only building in Toompea which survived a 17th century fire.
The first church was made of wood and built there most likely already in 1219 when the Danes invaded Tallinn. In 1229 when the Dominican monks arrived, they started building a stone church replacing the old wooden one. The monks were killed in a conflict between the Knights of the Sword and vassals supporting the Pope’s legate in 1233 and the church was contaminated. A letter asking permission to consecrate it anew was sent to Rome in 1233 and this is the first record of the church’s existence.
The building was completed in 1240 and it was a one-aisled building with a rectangular chancel. In 1240 it was also named cathedral and consecrated in honour of Virgin Mary. In the beginning of 14th century, reconstructions of the church began with building a new chancel. The enlargement of the one-aisled building to a three-aisled building began in the 1330s. The construction work however lasted almost 100 years and the new, longitudinal, part of the church was completed in the 1430s. The nave’s rectangular pillars had been completed in the second half of the 14th century, though.
The church was greatly damaged in the great fire of 1684 when the entire wooden furnishing was destroyed. Some vaults collapsed and many stone-carved details were greatly damaged- especially in the chancel. In 1686, after the fire, the church was practically restored to what it had been before. Pulpit with figures of the apostles (1686) and the altarpiece (1696) were made by Estonian sculptor and carver Christian Ackermann.
The Dome Church’s exterior dates from the 15th century, the spire dates from the 18th century. Most of the church’s furnishings goes back to the 17th and 18th centuries. From 1778 to 1779 a new baroque spire was built in the western part of the nave.
One should also mention a numerous sum of different kinds of tombstones from 13th –18th century, the stone-carved sarcophagi from the 17th century, also the altar and chancel, chandeliers, numerous coats-of arms from the 17th – 20th centuries. Two of the church’s four bells date back to 17th century, two date to the 18th century. The organ was made in 1914.
Among the people buried in the cathedral are the Bohemian nobleman Jindrich Matyas Thurn, one of leaders of Protestant revolt against emperor Ferdinand II and in events that lead to the Thirty Years War, Swedish soldier Pontus De la Gardie and his wife Sophia (John III's daughter), as well as the Scotsman Samuel Greig (formerly Samuil Karlovich Greig of the Russian Navy) and the Russian navigator Adam Johann von Krusenstern.
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.
