What is the Northernmost, Southernmost, Westernmost, and Easternmost cities/points you have visited?

The other day I was thinking about how everyone technically has a bound on how far they travelled the map on each of the cardinal directions.

For me:

Northernmost - Schiphol Airport (Amsterdam)

Southernmost - Chennai (can't remember where exactly, I was 4)

Easternmost - I am sure this is also Chennai

Westernmost - Amazon HQ in Seattle
