Sunday, Dec. 9 was a big day for a lot of couples. 140, to be exact.

And that's only counting the ones who got married on Sunday at Seattle City Hall, which was transformed into wedding central for one day to accommodate for the eager same-sex couples on the historic first day they were able to get married in Washington State. Couples had already been getting married since midnight.

From 10 a.m. and into the evening, couples walked out of City Hall and down the stairs through a cheering crowd. A free reception in honor of the couples was held at the Paramount at 6 p.m.

Photographer Heather Nelson was there to capture the moment on camera. Click on the main picture above to view the slideshow or browse through the thumbnails below.
