The Marina Bay Street Circuit sits on public roads that wind around the waterfront area on the southern coast of Singapore's main island. Some of the roads were designed and built specifically for the circuit, others are genuine street circuit fare.
It was initially designed by Hermann Tilke, then for whatever reason modified by a company called KBR. They're an American engineering and private military contractor with no known expertise in F1 circuit design.
Are you not reassured?
It's bumpy and slow with few overtaking opportunities, and there's little evidence it's particularly popular with the drivers. The heat, humidity and never-ending series of corners makes it one of the toughest races of the season.
On the bright side it looks like a great race to attend if you're a fan. And the race is held at night under floodlights, which makes the place look rather beautiful.
Turns 1, 2, 3 and 4
A lap begins with a decent-length run down to Turns 1 and 2, a medium-speed left-right combination. There's plenty of run-off on the outside of the first corner, so expect some drivers to risk a punt around the outside on the opening lap.
Turn 3 is a slower left-hand hairpin which follows immediately after Turn 2, and Turn 4 is one of those barely-perceptable left-hand kinks which always get a corner number on Tilke circuits.
Turns 5 and 6
After a short straight, the circuit drifts ever-so-slightly to the right for the tricky braking zone of Turn 5. This is a tight right-hander and one of the most important corners to get right because it leads onto the circuit's longest full-throttle zone.
Turn 6 is the right-hand kink halfway down, taken flat-out. The section of straight after this is the circuit's best overtaking spot.
At the end of the two halves of the straight comes Turn 7. It's a standard 90-degree left, and the scene of several overtakes down the years.
There's plenty of space to run wide, and most drivers will put at least two wheels well over the kerb (which appears to just be planted in the middle of nowhere) on the exit.
Turns 8 and 9
Turn 8 follows after a tiny straight, a standard 90-degree right, and Turn 9 is a slightly more open (but still 90-degree) left which leads onto a decent-length straight.
Ah, the Singapore Sling. The horrible, fiddly little chicane described by Lewis Hamilton as "ridiculous" and "pretty much the worst corner I've ever driven in Formula One."
He (and the entire grid, along with a few dozen suspension engineers and several million fans) will be relieved to learn it's gone. In its place is a single, medium-speed left-hander.
It was originally created as a slow chicane because there's no space for run-off at the exit, but there'll now be an extra layer of TecPro barriers in place.
The Sling was horrible, I'll kind of miss it.
Turns 11, 12 and 13
With the higher speed through Turn 10, the chicane which makes up Turns 11 and 12 will come at the drivers a little bit quicker, so earlier braking will be required.
The chicane is a left-right combo which slows the cars before the Anderson Bridge.
It's extremely narrow, and fortunately it's not a tempting overtaking spot.
Turn 13 is a tight, hairpin left which comes just after the cars drive off the bridge.
A straight follows, directing the cars up Esplanade Drive and over the second bridge of the lap. It's only a short straight before braking for Turn 14, which is on the same road junction as Turn 8. This one's another near-90-degree corner.
Overtaking may occur into here, but it'll be tough.
Turns 15, 16 and 17
The next section seems like someone decided there just weren't enough corners. But they keep the drivers nice and busy.
Turn 15 is a flat-out left kink just before braking for Turn 16, which is a slow right-hander leading into a slightly quicker left (Turn 17).
This is where Nelson Piquet Jr. intentionally crashed in 2008, letting teammate Fernando Alonso take advantage of the safety car deployment to win from 15th on the grid.
Turns 18 and 19
After a tiny straight comes one of the circuit's more interesting corners, Turn 18. It's a very tight 90-degree left-hander which steers the cars through a pseudo-tunnel under the grandstand.
The barriers on the outside have been known to collect the odd car or two over the course of the weekend, so expect to see at least one shunt before the race is over on Sunday.
The tunnel is very short and at the exit is Turn 19, yet another 90-degree right.
Turns 20 and 21
Turns 20 and 21 are a slightly more open, reversed copy of 18 and 19—right-left instead of left-right. There's also a little bit more run-off here, and no tunnel.
Turns 22 and 23
The cars then head down a short straight towards the fast left-handers of Turn 22 and 23. These two are the final (and probably the most fun to drive) corners of the lap. The first requires a touch of the brakes before turn-in, the second is flat out.
We're now back on the pit straight, and the start-finish line is only a short distance along.
The pit lane entry is on the inside just before Turn 22, and the exit feeds into the outside of Turn 2.
