Places no longer there are due to "progress?

Hi Gail, as for London...
The Elizabethan pub called the 'Fox and Firkin' was where an unknown Jimi Hendrix once went in early January '67 to celebrate having just had portraits taken for his upcoming debut album. That pub remains right at the Kew tube stop, but has been re-named 'Tap on the Line'. Jimi and his pair of new bandmates had gone an hour earlier to nearby Kew Gardens to have their abovementioned fotos taken. The fan that took those shots recently said, "Thank God that we'd arranged for a driver to take us all back to London. An incredible amount of Afghani hash was smoked by all in that pub's back patio!"

As for Toronto...
Joni Mitchell's famed lyric about paved paradises may well have been written about Toronto's Yorkville neighbourhood, a place where she once performed at tiny coffee-houses. A colleague of mine used to bring an impoverished and pregnant Joni groceries from time to time. By God has that neighbourhood ever changed, from funky-boho hippie-central to exclusive high-end shopping area for the very rich.

As for Liverpool...
The original Cavern Club was thoughtlessly mowed-over for a parking lot. Were there no city officials who said then, "WAIT! This club could be a tourist mecca ($$$$$$$) for us further down the road!"

I am done. The end

Old Corner Book Store in Boston (built in 1718 as an apothecary shop, then a bookstore in 1828) is now a Chipotle 🤨

My overall experience in Europe when I have gone back to places that I visited years ago that little has changed.

That was not the case in visiting countries like the former DDR, Poland, Czechoslovakia, Hungary, Yugoslavia and Bulgaria.

I visited all those countries in the 80s before the collapse of the Berlin Wall and the Communist governments there. Much has changed, for the better it is amazing.

Still, places like Venice, Florence, Rome, Paris, Munich, etc. little has changed. Berlin has changed a lot. London has changed more than most.

The Beatles bring in £82 million annually to Liverpool and over 2,300 jobs. That's truly amazing.

We attempted to visit the new Cavern Club but the street was a sketchy scene with loads of super drunk people. The tour of McCartney and Lennon homes was nothing short of fascinating.

I think you can find these in any city around the world. I know I scarcely recognize some of Seattle and I grew up here.

On a slight detour- My elderly father was quite excited when he found out my daughter and I were going to South Korea about 15 years ago. He asked me to look out for “the old tire factory “ so we could see where he bunked for a short time before moving north during the war. I dutifully figured out the location and took several pictures of the high rise that now stands on that location……. I think he truly expected that old tire factory to be there😀

The first time I was in Zurich, I stayed at the Pension St Josef, which was run by nuns. I went back a few years later and it was still there, just more expensive and run by a hotel company. It lost the character it had.

One place I have first hand experience with which fits your title is Berlin Tegel, formerly of the British sector.

I was there in July of 1973, Aug '84, Aug. '87, and the last time in Aug. of 1989, always flying in from Hannover-Langenhagen.

Places no longer there: A good number of small Pensionen and hotels.

The small hotel my second time in Paris in Aug 1977 down the block from the Metro station Cardinal Lemoine is gone, likewise with the Pension in Munich on the same trip,

The Pension on Kurfürstendamm where I stayed on all trips Berlin trips from 1971 to 1992 is gone. likewise the youth hostel in Vienna on Pulverturmgasse in 1971, as is the Gasthof in Salzburg in 1977....these places were "simply torn down."

My frequented restaurant around the block from the DJH hostel in Munich (1971) was torn down....all gone.

Yes, I stand corrected on the location of Tegel. Gatow is the site where the Luftwaffenmuseum is located after it had moved from Hamburg.
