Cathedral Square, Vilnius

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.

Kaziuko mugė or Saint Casimir's Fair is a large annual folk arts and crafts fair in Vilnius, Lithuania, dating to the beginning of the 17th century. The fair is traditionally held in city's markets and streets on the Sunday nearest to 4 March (Feast of St. Casimir), the anniversary of Saint Casimir's death. In Lithuanian, Kaziukas is a diminutive of Casimir. Today, Saint Casimir's fair also features music, dance, theater performances; it attracts tens of thousands of visitors and many craftsmen from across Lithuania as well as from neighbouring countries such as Latvia, Russia, and Poland. In recent years, the fair has expanded into other cities in Lithuania, Belarus, Poland.

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.

Pilies Street (literally, "Castle Street"; Lithuanian: Pilies gatvė) is one of the main streets in the Old Town of Vilnius, the capital of Lithuania. It is a rather short street, running from Cathedral Square to the Town Hall Square.Pilies Street is a popular location for market traders to sell the wares of folk artists. It has a natural advantage over the Town Hall Square as the street is generally busy and less likely to be interrupted by the political or cultural events commonly held at the Town Hall. Souvenir shops offer amberware and amber jewelry as well as linen clothes. The street is also known for the Kaziukas Fair, when folk artists from all over Lithuania gather here to display and sell their latest merchandise. Festivals in Vilnius frequently take place on Pilies Street – most processions will make their way through here at some point. This is true whatever the festival – be it Christmas, Easter, the day of Restoration of Independence, or just a spontaneous celebration following a major win for the Lithuanian basketball team. The headquarters of Vilnius University are located between Pilies Street and University Street, (Lithuanian: Universiteto gatvė). The House of the Signatories where the Declaration of Independence was signed on February 16, 1918 is also located on this street.

The Palace of the Grand Dukes of Lithuania (Lithuanian: Lietuvos Didžiosios Kunigaikštystės valdovų rūmai Vilniaus žemutinėje pilyje; Polish: Zamek Dolny w Wilnie) is a palace in Vilnius, Lithuania. It was originally constructed in the 15th century for the rulers of the Grand Duchy of Lithuania and the future Kings of Poland. The palace, located in the lower castle of Vilnius, evolved over the years and prospered during the 16th and mid-17th centuries. 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. According to the testimony of one of the couriers of Bona Sforza such initial reconstruction from 1520 to 1530 cost 100,000 gold ducats and was ordered by Sigismund I the Old. It is believed that the reconstruction was made for the proclamation ceremonies of Sigismund II Augustus, the only son of Sigismund I the Old, as the Grand Duke of Lithuania.

The Museum of Antiquities (Lithuanian: Senienų muziejus, Polish: Muzeum Starożytności) in Vilnius (Vilna, Wilno) was a museum of archaeology and history established by Count Eustachy Tyszkiewicz in 1855 at the premises of the closed Vilnius University. It was the first public museum in the former Grand Duchy of Lithuania and is considered a predecessor of the National Museum of Lithuania even though only a handful of items from the Museum of Antiquities ended up at the National Museum. Together with the Archaeological Commission which functioned as a de facto learned society, the museum was the most prominent cultural and scientific institution in all of Lithuania and displayed many historical items that reminded of the old Grand Duchy and served romantic nationalism of Lithuanian nobles at the time when Lithuania was part of the Russian Empire. The museum collections rapidly grew to over 67,000 items in 1865 by absorbing large collections of minerals and zoological specimens from the closed Vilnius University, libraries of various closed Catholic churches and monasteries, and various donations from local nobles. The museum was nationalized and reorganized after the failed Uprising of 1863, removing almost all items related to the former Polish–Lithuanian Commonwealth to the Rumyantsev Museum in Moscow. The museum became a division of the newly established Vilnius Public Library. The reformed library and museum served to support the official Russification policies and displayed many items related to the Russian Empire and the Eastern Orthodox Church. After losing the last significant cultural center that supported the culture of the former Grand Duchy of Lithuania, Vilnius was becoming a Russian provincial city and losing its leading role in Polish–Lithuanian cultural life. The museum continued to operate until World War I when its most significant holdings were evacuated to the Rumyantsev Museum. The handful of items that remained in Vilnius and were not lost during the wars are held by various museums, including the National Museum of Lithuania, the Lithuanian Art Museum, and the Geology and Zoology Museums of Vilnius University.

The National Museum of Lithuania (Lithuanian: Lietuvos nacionalinis muziejus), established in 1952, is a state-sponsored historical museum that encompasses several significant structures and a wide collection of written materials and artifacts. It also organizes archeological digs in Lithuania.
