The Cathedral School of Vilnius was a cathedral school attached to the Vilnius Cathedral. It is believed to be the earliest school in the Grand Duchy of Lithuania. For about a hundred years it was the only Catholic school in Vilnius (possibly due to a royal privilege prohibiting establishment of other schools). The cathedral school was merged with Vilnius Academy (now Vilnius University), established by the Jesuits in 1570. The exact date of its establishment is unknown, but it must be sometime between the Christianization of Lithuania in 1386 and school's first mention in written sources on 9 May 1397. It was initially a primary school, evolving into a secondary school by the first half of the 15th century. Most likely the school taught trivium and quadrivium and catered to church needs educating lower clergy. Its first pupils were indigenous Christians that also knew the Lithuanian language. In 1522, Bishop John expanded the school to three classes and introduced courses in rhetoric, dialectics, classical literature, arithmetic, music. The students studied Distichs of Cato and Ars grammatica by Aelius Donatus. In 1539, the school had twelve boys who sang in a church choir and twenty boys who served as altar boys. During its existence, the school prepared over 100 students who later pursued academic careers at the Jagiellonian University in Kraków.

The Cathedral Basilica of St Stanislaus and St Ladislaus of Vilnius (also known as Vilnius Cathedral; Lithuanian: Vilniaus Šv. Stanislovo ir Šv. Vladislovo arkikatedra bazilika; Polish: Bazylika archikatedralna św. Stanisława Biskupa i św. Władysława, historical: Kościół Katedralny św. Stanisława) is the main Catholic cathedral in Lithuania. It is situated in Vilnius Old Town, just off Cathedral Square. Dedicated to the Christian saints Stanislaus and Ladislaus, the church is the heart of Catholic spiritual life in Lithuania. The coronations of the Grand Dukes of Lithuania took place within its confines. Inside its crypts and catacombs are buried many famous people from Lithuanian and Polish history including Vytautas (1430), his wife Anna (1418), his brother Sigismund (Žygimantas) (1440), his cousin Švitrigaila (1452), Saint Casimir (1484), Alexander Jagiellon (1506), and two wives of Sigismund II Augustus: Elisabeth of Austria (1545) and Barbara Radziwiłł (1551). The heart of the Polish king and Grand Duke of Lithuania Władysław IV Vasa was buried there upon his death, although the rest of his body is buried at the Wawel Cathedral in Kraków. Inside, there are more than forty works of art dating from the 16th through 19th centuries, including frescoes and paintings of various sizes. During the restoration of the cathedral, the altars of a presumed pagan temple and the original floor, laid during the reign of King Mindaugas, were uncovered. In addition, the remains of the cathedral built in 1387 were also located. A fresco dating from the end of the 14th century, the oldest known fresco in Lithuania, was found on the wall of one of the cathedral's underground chapels. During the Soviet occupation, the cathedral was converted into a warehouse. Masses were celebrated again starting in 1988, although the cathedral was still officially called The Gallery of Images at that time. In 1989, its status as a cathedral was restored.

The Vilnius Castle Complex (Lithuanian: Vilniaus pilių kompleksas or Vilniaus pilys) is a group of cultural, and historic structures on the left bank of the Neris River, near its confluence with the Vilnia River, in Vilnius, Lithuania. The buildings, which evolved between the 10th and 18th centuries, were one of Lithuania's major defensive structures.The complex consisted of three castles: the Upper, the Lower, and the Crooked (Lithuanian: Kreivoji pilis). The Crooked Castle was burned down by the Teutonic Knights in 1390 and was never rebuilt. The Vilnius Castles were attacked several times by the Teutonic Order after 1390, but they did not succeed in taking the entire complex. Its complete capture occurred for the first time during the 1655 Battle of Vilnius. Soon afterwards, the severely damaged castles lost their importance, and many buildings were abandoned. During the Tsarist annexation, several historic buildings were demolished; many more were damaged during the fortress construction in the 19th century.Today, the remaining Gediminas Tower is a major symbol of the city of Vilnius and of the nation itself. Annually, on 1 January, the Lithuanian tricolor is hoisted on Gediminas Tower to commemorate Flag Day. The complex is part of the National Museum of Lithuania, one of the largest museums in the country.

For four centuries the palace was the political, administrative and cultural centre of the Polish–Lithuanian Commonwealth. It was demolished in 1801. Work on a new palace started in 2002 on the site of the original building and it took 16 years to complete it in 2018. The palace was rebuilt in a Renaissance style.
