Built in the 1770s and 80s, this elegant semi-circular palace in Łazienki Park was originally conceived as King Stanisław August's primary residence, though it gradually shifted to more diplomatic functions, hosting official state soirees and accommodating foreign ministers. Designed in Early Classicist style by Italian architect Domenico Merlini, the unique recessed entrance is decorated with mythological sculptures by Royal sculptor Giacomo Monaldi. After a thorough renovation, the building again appears very much as it would have in the late 18th century, and a walk through the interiors - replete with original murals, furniture and art - is worth the short amount of time it takes to see them.

Average visiting time: 30mins.
