I've read this thread and I'm going to chime in here with what might be an unpopular opinion, and I certainly mean no harm by it, just presenting another point of view.
Europe, like anywhere else, can be safe or dangerous depending upon where you go (as others have pointed out).
However, we are in hard times. We are approaching a global recession. Many people don't have money, are hungry, or have been sick in the Pandemic or lost loved ones. Addtionally, many in Europe are from places where there is war, famine, and severe climate change. Being sensitive to the tone of society might help you blend in better as a visitor, too.
I can see that one beloved Love bracelet might be on the arms of many in Europe, but three together could be interpreted as a more significant statement that equates to you having more resources.
Does wearing three indicate more wealth than the usual person, and make you a target for being followed and robbed in other ways?
if someone challenged you and threatened your life or your family's lives to remove them, would you be able to do so and give it to them? (The other TpF member's suggestion to carry the screwdriver is helpful). And would that be something that would scar your children and dampen your memories of the trip? I don't mean to scare you, but just thinking through scenarios.
I know what it is like to feel "bare" without the usual jewels. However, the Euro is at such a low right now, you might want to just get a smaller, thin Love (you know, for 'travel'

) while you are there, and leave the beautiful big ones at home.
I haven't travelled to Europe since 2019 because of the Pandemic, but I never take or wear any jewelry that can't be easily replaced. I wear sliver with a stainless steel or even swatch style watch for summer, and leave my beloved jewels at home.
I hope you have a wonderful trip and see marvelous things and stay safe, whatever you decide to do about your beautiful bracelets.
