The Latin Cathedral is Lviv's oldest standing cathedral, begun in the 14th century and built over the following two centuries in a mixture of Gothic and Renaissance styles. It stands in Cathedral Square, slightly off the main tourist flow, which means it's often quieter than Rynok Square despite being one of the most important buildings in the city. The interior retains medieval chapels, Renaissance altarpieces, and Baroque embellishments — a layering of centuries of patronage and piety.
The adjacent Boim Chapel is architecturally among the most remarkable buildings in all of Ukraine: a small funerary chapel covered in an extraordinary density of carved stone decoration, commissioned by a wealthy merchant in the early 17th century. It is worth seeking out even if the cathedral itself is closed. The square also contains the remnants of the city's early fortifications and the Bishop's Palace.
