I start big.
With a prime number.
In the letter A, I will tell you about something special and so dear to all Swedes.
Allemansrätt in Swedish, Right of Public Access in English
is a freedom granted by the Swedish Constitution which says that despite the right to own property, "everyone should have access to the countryside under the right of public access."
Many Swedish people consider this to be a form of legacy or human right. Thus to put up a 'no trespassing' sign would be considered a violation.
Smile.
However, there are laws that restrict allemansrätten, in order to protect vulnerable areas for example. But as long as you don’t camp in someone’s garden, leave rubbish or cause any damage, you normally have the right to roam freely in forests, have a swim in someone else’s water, put up a tent and stay for a couple of nights and pick wild berries and mushrooms.
Welcome to Sweden.
