The coffee shop economy has quietly made sitting down a purchase. These eight have not got the memo, and most of them are free.

There is a particular London arithmetic that everybody does and nobody mentions. You want to sit somewhere warm for two hours. A coffee is four pounds fifty. Two hours is, by unspoken agreement, two coffees. So sitting down costs nine pounds, plus the low background awareness that the staff would like the table back.
None of that is anybody's fault. Rent is what it is. But it does mean that a genuinely free place to sit, indoors, for as long as you like, has become an unusual thing rather than an ordinary one.
Here are eight, and the only thing they have in common is that nobody in them is waiting for you to go.
A jungle inside the Barbican's concrete. Palms, ferns and koi, under glass, in the middle of the City.
It is free, it is enormous, and most Londoners have either never been or went once and forgot it existed. Check the opening days before you go, because it is not open every day of the week, and there is no sadder walk than the one back out of the Barbican having got the day wrong.
Neo-gothic, with a twelve-sided domed reading room that looks invented for a film.
It belongs to King's College, so access depends on what is on and who you are, which is worth checking first. When it is open to look round, it is one of the most extraordinary interiors in central London and almost nobody photographs it, which tells you how few people go.
The largest collection of modern poetry in the country, on the fifth floor of the Southbank Centre, free to walk into.
You do not have to like poetry. You have to like a quiet room with a view of the river and armchairs that nobody is monitoring. The staff will leave you completely alone, which on a wet Tuesday is the entire offer.
The copper-clad one that won the Stirling Prize, and still looks like nothing else in London.
Public libraries are the last indoor spaces in the city with no transaction attached, and this is the one worth travelling for. Bring a book you have been failing to start.
Red brick outside, chequerboard floors and a stained-glass apse inside.
An apse. In a library. It is the sort of building that would be a wedding venue if anyone had thought of it, and instead it is a working local library where you can sit down for free and read the paper.
Inside the Barbican complex, so you can arrive from the station without meeting the weather.
Pair it with the Conservatory above and you have most of a wet afternoon in one building, with a concert hall and a cinema attached in case you want the day to escalate.
Warm, calm, and dangerously easy to lose time in, which is the venue's own description and is more honest than most retail copy.
Five floors, chairs on most of them, and a genuinely relaxed attitude to people reading books they have not yet bought. There is a bar at the top if the afternoon takes a turn.
Twenty pounds, a historic independent library five minutes from Piccadilly Circus, and the only entry on this list that costs anything.
It is included because it is the logical end point of the whole idea: a members' library with a million books and the kind of silence that money buys. Worth knowing about for the day you decide that free is no longer quiet enough.
Seven of these eight cost nothing at all. If that is the part that appeals, everything free on the site is in one place, and there are eighty-eight of them.
And if what you actually want is quiet rather than free, quiet, calm and nearly empty is the collection for that.
