Alder Ballroom


A versatile event space in the heart of downtown Portland.

As our largest meeting space, the Alder Room can accommodate up to 60 guests for banquets or events. With arched floor-to-ceiling windows, custom chandeliers and views of the city, this beautiful venue can also be divided into two separate rooms – Alder East and Alder West – adding to its versatility.
