three centre arches in amsterdam

The arches seen here (there are four of them:-) on a canal in Amsterdam could quite possibly be either three centre or elliptical. One would have to have a very keen eye to tell the difference. I have used my CAD program to superimpose one on the other and I was quite surprised by the closeness of the results.
