Pordenone's cathedral, dedicated to San Marco, stands near the northern end of the Corso and contains some of the best artwork in the city, including a notable altarpiece by Giovanni Antonio de' Sacchis (Il Pordenone) and significant works by Licinio and Pordenone's school. The exterior is a somewhat restrained Renaissance-Baroque composite; the interior is richer and more surprising.
The freestanding campanile alongside is one of the city's landmarks. The cathedral is open throughout the day and entry is free, making it a natural stop on any walk along the corso.
