The world’s first steam powered clock is in the Gastown neighborhood of Vancouver, British Columbia, Canada. This plaque tells about it.
Glass panels on the sides allow the curious visitor to see the mechanics inside this clock.
Another photo showing the whole clock is in my previous post.
For more timepieces and other interpretations of the theme time, see Becky’s December Squares.
Speaking of time, here’s a video of the lyrics to the song Time Has Come Today by the Chambers Brothers.
