Free things to do this weekend

Everything here is listed by its organiser as free or pay-what-you-like. Sometimes you have to sign up first, or the organiser asks for a donation (that is stated with the outing), so check the organiser's site before you go.

We put everything that is free in order of what makes it special: one-off or not, who plays, how well it fits the season. Where we can, a pick says why.

Online events, lectures, courses, weekly classes, church services and business meetings. And anything that is only free for members or with a pass.

In summer, when there are free festivals on squares and in parks. In autumn and winter you mostly find free concerts and exhibitions indoors.
