Yesterday while I was booking some London sightseeing, I found this free app listed on the Wallace Collection (free museum) website. There are 300+ smaller museums listed, many in the US and England/Scotland, some in France and a several in other countries including Italy and Japan.
Some museum guides are audio, others are written. As I scanned through the list, I saw Ann Frank Huis, British Library, National Gallery, Musee Carnavalet, Chateau de Vincennes.
You get the idea. Lots of free guides. ❤️Save the ones you want for your trip to make them easier to find. I downloaded the app from the Apple App Store. Logic (?) says it should be available for Samsung.
