What do you call the objects that make you remember other things or that you keep to remember a moment or a place? I mean souvenirs, photographs, etc.
- an object or item that serves to remind one of a person, past event, etc.; keepsake; souvenir.
- anything serving as a reminder or warning.
They offered tea, a smoke, and an Egyptian flag as a memento.
Definition №1 is probably most relevant here, even using the word you mention.
A little old-fashioned, but still perfectly good, and in my opinion, rather charming:
something that helps you remember a person, place, or occasion: Her aunt gave her a little wooden elephant as a keepsake.
I think this fits very well with the question (something that you keep to remember a moment or a place).
It is a rather self-explanatory answer and to those who doubt it, this phrase is used: Ngrams
Those who were given the cassis smell remembered more details about the film and found their memories more unpleasant and arousing than those who had the background music as a memory trigger, although the lights and the smell were equally effective.

1.An aid to the memory, especially a book or document.
‘His hundreds of sketchbooks were invaluable aide-memoire, and he kept them well organized so he could quickly locate what he wanted.’
‘These photos later served as aides-memoires for the large decorative panels.’.

If the object doesn't evoke a memory personal to the owner, memorabilia might be a good term.
objects kept or collected because of their historical interest, especially those associated with memorable people or events.
"World Series memorabilia"
archaic - memorable or noteworthy things.
It could be called a mnemonic object which the "Memory Techniques Wiki" explains in more detail:
The "mnemonic object" method is based on the Von Restorff Effect, which says that items that stand out are more easily remembered. By placing a familiar object in an unfamiliar context, you can intentionally trigger the recall of a memory when that out-of-place object is seen again.
In Italian, we like to say "ricordo" (another word for a souvenir or momento) or the more commonly used word, "bombiniere" (a keepsake given at celebrations).
Hope this helps :)
