The Guinness World Record Largest Open Sandwich; It was a barbecue pork bun (as of July 2010; dunno if the record still stands)

My hometown was a well-known regional port and was the home of a "medical" serial killer (both in the early 20th century) who was responsible for over 15 deaths over 4 years.

We won three wars against the UK in the 19th century.

One of the worlds most useless canals goes through my town (on it's path to crossing the entire width of the country). It was built largely with russian POW's. However, roughly eight years before it was completed, steam locomitives became a thing, making it obsolete.

My city is build around 60 volcanic hills.

My hometown was most notable for a husband and wife serial killer pair who preyed on young girls in the area. This one will be easy to guess.

It has Asia's largest saltwater lake

More navigable waterways than any other US state. (From there but no longer live there).

My city has the most strip clubs per capita in the USA

The city I'm from has more bridges than Venice and Amsterdam combined.

There's a catholic cathedral that was designed by a protestant and a protestant cathedral that was designed by a catholic.

We’ve decriminalized magic mushrooms.
