Whoa. There are around 4 Masonic Lodges in Portland. They need that many? I looked them up and found two with possible murals. This one is the largest lodge with murals. First page you see is two guys out front and there is a mural but they are pretty secretive about showing anymore of the building. The way you described it, I think this is the one. It has pillars. I don't navigate too well with the google. But will try some more. With what we have been finding lately in Oregon, Voodoo Donuts and the tunnels I am not surprised there are so many Masonic Lodges. Wonder how many there are in the state. friendship160 They also have a deMolay in the area which is a Higher Level of the Masonic Order. Bill Clinton is a member of that as well.

Here us a link to an interesting article about Freemasons in Oregon. https://www.southeastexaminer.com/2015/06/freemasonry-in-oregon/

Oregon currently has approximately 110 ‘blue’ lodges, the basic Masonic unit accommodating the first three ‘degrees’ of Masonry. As might be expected, the majority of these follow the state’s population pattern; that is Portland, the I-5 corridor, the coast, and the Columbia River. At last count there were 8,600 blue lodge members. But that is just the proverbial tip of the iceberg! The Oregon Masonic family has literally scores of ancillary bodies. The two most prominent are the York Rite and the Scottish Rite with all their intermediate degrees. The Scottish Rite numbers its degrees up to 33. The York Rite names theirs, the highest being the Knights Templar. Blue lodge members may belong to either or both of these, or none. It remains their choice. And of course there are numerous honorary associations catering to every taste and fancy. Add to this all the national and international levels and you begin to get the scope of Masonry.

110 "blue" lodges? Wow.
