Korniakt Palace

Count the windows. Every merchant house on Rynok Square was allowed three across its front — a rule of the medieval city, and a marker of rank. The palace at number 6 has six, on every floor. That doubling is why people who have never been inside still know the building: the widest, grandest house on the square, its Renaissance facade standing clear of the painted terraces on either side. Locals call it the Korniakt Palace, after the merchant who built it, and the Royal Townhouse, after the king who later owned it. The best of it hides at the back — a quiet arcaded courtyard the city named after Italy.

The merchant who was allowed six windows

The Korniakt in the name is Kostiantyn Korniakt, a Greek from Crete who reached Lviv in the 1560s and became the richest man in it. He traded Malvasia wine by the barrel and collected customs duties for the crown; in 1571 King Sigismund II Augustus ennobled him, and under his successor, Stephen Báthory, Korniakt won leave to break the rule of the facade. Under Magdeburg law the number of windows was fixed by rank — three for an ordinary burgher — and the exception granted him was a privilege money alone couldn't buy. The palace rose in 1580 on the footprint of two older Gothic houses, at a scale to match the man who paid for it.

A Renaissance palazzo on the square

It is one of the purest pieces of Renaissance architecture in Lviv, built by men who knew the idiom at first hand: the Italian-trained masters Pietro di Barbona and Paolo the Roman — in Ukrainian, Pavlo Rymlyanyn — who between them worked on several of the city's landmark buildings. The carved portal still shows the date 27 Ap 1580, the year the work was done. A hundred years on, the roofline was dressed in the Baroque taste, an ornate attic of statues added around 1678. And behind the Renaissance walls a stranger thing survives: a secular Gothic hall from the 15th century, left over from the houses that stood here before Korniakt cleared them.

The Italian Courtyard

The showpiece is out of sight from the square. Walk through the building and you reach the Italian Courtyard, a small inner court wrapped on three sides by open galleries stacked three storeys high. The likeness to the patio of a Roman or Florentine palazzo is what earned it the name. It is startlingly quiet — the thick walls seal out Rynok, and the arcades hold a hush closer to a museum than a city centre. The courtyard you photograph, though, is younger than it looks. The loggias were rebuilt in the early 20th century, finished by the architect Wawrzyniec Dayczak around 1931, so they are barely a century old even where the house behind them is four. In warm months the court turns stage — jazz and classical concerts, theatre, and a summer café where you drink your coffee under the arches.

How it became royal

Korniakt's heirs sold the house in the 1620s to the Discalced Carmelites, and in 1640 it passed to Jakub Sobieski. His son inherited it — the future king Jan III Sobieski — who made it a royal residence and gave the palace its second name. Its heaviest moment came in December 1686, when Sobieski, by then king, swore to the Treaty of Eternal Peace with Muscovy in one of these halls. The treaty itself had been signed in Moscow that spring; it split the Ukrainian lands along the Dnipro and handed the Left Bank and Kyiv to Russia. The house then changed hands among noble families for two more centuries, until the city bought it in 1908 for a museum.

Visiting

The palace stands at Rynok 6, on the eastern side of the square a few steps from the Town Hall, and the whole Old Town is walkable. Inside is the Lviv Historical Museum, so you enter with a ticket during opening hours; the Italian Courtyard is usually ticketed separately, and for most people it is the reason to come. Time it for the warm season, when the court is open and the café is running — better still, for one of the concerts, when the old arcades fill with music. Rynok Square belongs to Lviv's UNESCO-listed historic centre, and this is one of its finest houses. Come for the facade; don't leave without walking through to the courtyard behind it.
