1. a place where you are protected from harm or danger
a safe haven for victims/survivors/refugees
This expression is usually used in one of two different ways. Firstly, a 'safe haven' can refer the official protection a country gives to a person or group of people who come from another country where they are at risk due to war, famine, or some other factor. Secondly, a 'safe haven' can refer to a place, activity, or situation that provides somebody with the chance to escape from something stressful or unpleasant. It is much more common in a social context but can be used in a professional one in relation to an investment that is unlikely to lose value and comes with few risks.
