Palace of the Grand Dukes of Lithuania

The Palace of the Grand Dukes of Lithuania stands on Cathedral Square in Vilnius, beside the Cathedral Basilica and directly below the Gediminas Tower that crowns the Upper Castle above. The three elements — cathedral, lower palace, upper tower — form the historic nucleus around which the medieval city grew, and together they represent the political and spiritual architecture of a state that was, at the height of its power, one of the largest in medieval Europe.

The Grand Duchy of Lithuania's territorial peak came in the 15th century, when the state stretched from the Baltic Sea in the northwest to the Black Sea coast in the south — covering roughly the area of present-day Lithuania, Latvia, Belarus, Ukraine, and significant parts of Poland and Russia. This was not a peripheral or marginal state but a major European power, with a court that attracted Italian architects, Flemish craftsmen, and diplomatic delegations from across the continent. The palace on Cathedral Square was the physical expression of this ambition: a Renaissance and Baroque complex whose ceremonial halls and royal apartments were designed to project the cultural sophistication appropriate to a European dynasty.

The palace's history has an unusual arc. It was demolished under Russian imperial rule in the early 19th century — part of a broader policy of erasing Lithuanian state symbols — and the site was built over. Archaeological excavations in the late 20th century rediscovered the foundations and, crucially, established the palace's groundplan and partial elevation with enough precision to support a historically documented reconstruction. The current building, completed in 2018, was erected directly over the excavated foundations; the archaeology has not been disturbed but preserved beneath the new construction, visible through glass floors in Route I.

The museum is structured around two routes that the GYG guided tour (t1384661) covers in sequence. Route I descends to the archaeological level, where the medieval and early modern foundations are displayed in their original positions; visitors walk the actual groundplan of the 14th–16th century palace while the guide explains what each space was used for. Route II moves through the reconstructed upper floors — the ceremonial halls furnished with period pieces, the royal apartments, and the three-storey Renaissance courtyard that served as the ceremonial centre of the palace complex. The Observation Tower completes the visit with views over Cathedral Square, the Cathedral, and the Gediminas Tower rising above on its limestone cliff.

The tour (t1384661) runs in small groups with a licensed guide — a significant advantage over self-guided visiting at a site where the relationship between the visible reconstruction and the invisible archaeology requires explanation to be fully understood.
