Zeven Brugen? Ah, it's bruggen! :Dank u Jamill!

Is the plural of brug (bridge) brugen?

 

At some point along the canalboat tour, we're told that you can see seven arched stone bridges from the canal.

 

After studying and analyzing my map, I can find two places where one should be able to see seven bridge arches: either Reguliers Gracht (Reguliers Canal) between Herengracht and Lijnbaansgracht (Lijnbaans Canal),

 

or

 

Along Leidsegracht between Singelgracht and Herengracht.
