I often find that searching for a place... for example, London, will bring up many links, but usually near the top of the list is the Wikipedia article-- at least for most site with names.
thus https://en.wikipedia.org/wiki/London

In the upper right corner will be the clickable HTML to the coordinates... clicking it takes to the "Geohack" page
for 51° 30' 26? N, 0° 7' 39? W

This gives a list for many map links. I use almost entirely the GoogleEarth links, (but you may find some items of special interest).... If you have G.E. installed, these will download and send the correct address to G.E. and start it up and take you directly to a spot over London.
   From there, you can browse..or enter specific search terms...

Play with it.. or use the Wikipedia + Geohack links to do many things.. I seldom find sites that show coordinates as well or in a clickable format as Wikipedia.
