Palindromic Place Names

Anu Garg’s A.Word.A.Day newsletter theme of the week (August 26, 2019) was palindromes words which read the same forwards and backwards.
In the weekly follow-up newsletter, Richard Stallman pointed out that Neuquén, Argentina, has a name that is a seven-letter palindrome and wondered if any place names were longer palindromes.
I wondered, too, so I ran a little program on the geonames.org database of almost 12 million place names. The answers depend on the rules for the search, so I grouped the results into the tables below. Click on the name to google for more information or click the globe icon to find the place on the map. The two letter country codes are decoded at iso.org.
In 2011 a similar query led me to list the longest Isogrammic Place Names having no repeating letters.
