That hut looks more like a place to down some high altitude margaritas than a Starbucks.

Cocktails in the library each evening.

I have a suggestion for this thread:

Once a puzzle is solved, it would be very cool if the author of that puzzle would edit the original message, and post some sort of answer/information/links within a "spoiler" box... like this

To make something like the above, all you need to do is enclose the hidden text within a [spoiler:The Answer] ... [/spoiler] pair of tags.

You have one of the places, but not the event.

These places made an impression on Claude Monet

yes, the island is the first picture

the second picture with the palace named in Alan's clue has a famous small bridge behind it, not seen in the picture, but it connects the old prison to the interrogation rooms in the palace. So maybe someone famous got grilled.

I figured that Monet painting it was enough of an event.

wagga?

Two places, something connected them?

Sigh

No, not a bridge.

Does not a high-bandwidth transmission at 2.4 GHz constitute a bridge? Maybe a Fabrizio Bridge.

Galileo demonstrated his improved telescope from these bell towers. Getting warmer?

This is the Capanna Regina Margherita at about 14,816 feet above sea level, on the Italian/Swiss border.

Here is a terrific pano.

It is at a similar height to our very own Smithsonian hut. Even though it has electrical power, 70 beds and a library, alas, it does not have a Starbucks.

This may be a very important discovery. On the other hand I have a neighbor working diligently on building a perpetual energy generator. Who knows?

A team of Italian radio boffins - and one Swede - have one-upped their pioneering countryman Guglielmo Marconi by demonstrating a method of simultaneously transmitting multiple signals on the same frequency.

Let radio do the twist.

Here is the site of a ripping yarn, close to home.

I should have ID'd that one. The Monte Rosa hut was famous for high altitude medicine research:

The Monte Rosa is not only mountain climbing, history and passion but also science. There are two science laboratories operating up there: the Capanna Margherita at the Signalkuppe at an altitude of 4,554 meters and the Istituto Angelo Mosso at Col d'Olen at 2901 meters. Capanna Margherita has been inaugurated in 1893 on behalf of the Italian Alpine Club (CAI) and since the very beginning it has been a scientific laboratory of international repute. In 1903 it has been declared "International Institute" by the Academy of Sciences in Washington and through the XX° century it hosted the most innovative researches in different scientific areas: physiology and medicine (63%), glaciology (20%), environmental sciences ( 15%), physics (2%)

Harvey, we aim to please.

OK, I recognize the insignia and it is desert. We'll get there.
