If you are walking in Pioneer Square in the area of the stadiums, go to the King Street Station, a National Registered Historic Place that is worth a small visit.
Seattle’s main Amtrak station was built in the beginning of the twentieth century. The red brick clock tower was modeled after Campanile di San Marco in Venice, Italy.
The building renovation finished last year. You can now see the nice hand-carved coffered ceiling, a balcony and a second level of arches. The lobby is a clear and nice room where you can sit for a while. It may be quiet and empty, or busy and noisy depending of course on the train schedule.
As they were hidden by a lower ceiling, I was not able to see all these details 8 years ago when I arrived from Europe with my family on the Empire Builder train from Chicago.
