Seattle Monument / Memorial

The dictionary definitions are...

monument: A statue, building, or other structure erected to commemorate a famous or notable person or event
memorial: Preserving the memory of a person or thing; often applied to an object set up, or a festival (or the like) instituted, to commemorate an event or a person.

-----------------------

I think differences between monument and memorial is, monument focuses on one notable event or person, but memorial is more general.

I will chose Space Needle as a monument of Seattle, since it was built to celebrate the 1962 Seattle's World Fair. Although not many people remembers 1962 World Fair any more, Space Needle became a symbol of Seattle and recognized by visitors.
For the memorial building, I will chose The Broadway Performance Hall in Seattle Central Community College. The Broadway Performance hall was a original building of Broadway High School which was the first high school in Capitol Hill. The high school transformed to technical school after the WW2 and right now it became a part of Seattle Central Community College. The Broadway Performance Hall went through the history of development of Seattle and with unique culture around the broadway, it is definitely a Seattle memorial building.
