Rotterdam canal bridge (#0198)

Just an older canal bridge and lifts in Rotterdam center. It would be interesting to know more about the age of the tower/lifts, but I couldn't find anything. There are actually four lifts for the span, one on each corner. One is invisible, obscured by the lift that is closest to me. You can barely see the fourth lift – the historic tower was removed and the lift is built into the modern building on the left side of the picture.
