The Trinity Lavra of St. Sergius is the most important Russian monastery and the spiritual centre of the Russian Orthodox Church. The monastery is situated in the town of Sergiyev Posad, about 70 km to the north-east from Moscow by the road leading to Yaroslavl, and currently is home to over 300 monks. The monastery was founded in 1345 by one of the most venerated Russian saints, Sergius of Radonezh, who built a wooden church in honour of the Holy Trinity on Makovets Hill. Early development of the monastic community is well documented in contemporary lives of Sergius and his disciples.
In 1355, Sergius introduced a charter which required the construction of auxiliary buildings, such as refectory, kitchen, and bakery. This charter was a model for Sergius numerous followers who founded more than 400 cloisters all over Russia, including the celebrated Solovetsky, Kirilov, and Simonov monasteries. St. Sergius supported Dmitri Donskoi in his struggle against the Tatars and sent two of his monks, Peresvet and Oslyabya, to participate in the Battle of Kulikovo. At the outbreak of the battle, Peresvet died in a single combat against a Tatar bogatyr. The monastery was devastated by fire, when a Tatar unit raided the area in 1408.
St. Sergius was declared patron saint of Russian state in 1422. The same year the first stone cathedral was built by a team of Serbian monks who had found refuge in the monastery after the Battle of Kosovo. The relics of St. Sergius are seen in this cathedral, dedicated to Holy Trinity. The greatest icon painters of medieval Russia, Andrei Rublev and Daniil Chyorny, were summoned to decorate the cathedral with frescoes. In 1476, Ivan III invited several Pskovian masters to build the church of the Holy Ghost. This graceful structure is one of the few remaining examples of a Russian church topped with a belltower. The interior contains the earliest specimens of the use of glazed tiles for decoration. In the early 16th century, Vasily III added the Nikon annex and the Serapion tent, where several of Sergius' disciples were interred.
It took 26 years to construct the six-pillared Assumption Cathedral, which was commissioned by Ivan the Terrible in 1559. As the monastery grew into one of the wealthiest landowners in Russia, the woods where it had stood were cut over and a village sprang up near the monastery walls. It gradually developed into the modern town of Sergiyev Posad. The cloister itself was a notable centre of chronicle-writing and icon painting. Just opposite the monastery walls St. Paraskevas Convent was established, among whose buildings St. Paraskevas Church, Introduction Church, and a 17th-century chapel over St. Paraskevas well are still visible.
In 1550s, a wooden palisade surrounding the cloister was replaced with 1.5 km long stone walls, featuring twelve towers, which helped the monastery to withstand a celebrated 16-month Polish Lithuanian siege in 1608–1610. A shell-hole in the cathedral gates is preserved as a reminder of Wladyslaw IV's abortive siege in 1618. By the end of the 17th century, when young Peter I twice found refuge within the monastery from his enemies, numerous buildings had been added. These include a small baroque palace of the patriarchs, noted for its luxurious interiors, and a royal palace, with its facades painted in checkerboard design. The refectory of St. Sergius, covering 510 square meters and also painted in dazzling checkerboard design, used to be the largest hall in Russia.
In 1744, Empress Elizabeth conferred on the cloister the dignity of the Lavra. The metropolitan of Moscow was henceforth also the Archimandrite of the Lavra. Elizabeth particularly favoured the Trinity and annually proceeded afoot from Moscow to the cloister. Throughout the 19th century, the Lavra maintained its status as the richest Russian monastery. A seminary founded in 1742 was replaced by an ecclesiastical academy in 1814. The monastery boasted a supreme collection of manuscripts and books. After the Russian Revolution of 1917, the Soviet government closed the lavra in 1920. In 1930, monastery bells, including the Tsar-Bell of 65 tons, were destroyed. Pavel Florensky and his followers could hardly prevent the authorities from stealing and selling the sacristy collection but overall many valuables were lost or transferred to other collections.
In 1945, following Joseph Stalin's temporary tolerance of the church during World War II, the Lavra was returned to the Russian Orthodox Church. On April 16, 1946 divine service was renewed at the Assumption Cathedral. The lavra continued as the seat of Moscow Patriarchy until 1983, when the patriarch was allowed to settle at the Danilov Monastery in Moscow. After that, the monastery continued as a prime centre of religious education. Important restoration works were conducted in the 1960s and 1970s. In 1993, the Trinity Lavra was inscribed on the UN World Heritage List. The Lavra has a number of outreach offices in its vicinity and throughout Russia. The Lavras hieromonks have manned a number of sketes at remote locations, as well as the Trinity Church on the King George Island in the Antarctic.
The monastery was founded by Saint Ferapontov in 1398 in the inhospitable Russian North, to the east from the Kirillo-Belozersky Monastery, named after his fellow monk, Saint Kirill of Beloozero. The fame of the monastery started to spread under Kirill's disciple, Saint Martinian, who was to become a father superior of the Troitse-Sergiyeva Lavra in 1447.
In the Time of Troubles, the monastery was ravaged by the Poles. During its recovery the last buildings the tent-like church of Saint Martinian 1641, a two-tented barbican church, and a bell tower was added to the complex. The belfry clocks are said to be the oldest in Russia.
