What It Means: Sydenham (Cippa's Home) was a wooded Kentish village until the railway arrived in 1852. The original palace was moved from Hyde Park three years later. South Norwood, where they play now, was part of the Great North Wood, although most of the remaining woods are now golf courses. Sel-hurst was literally Willow Hill.
Why it's There: thanks to a Geordie and a German. Stephenson's railways created classic suburbia, the setting for zillions of sitcoms (well situations, there wasn't much comedy in some of them), especially from LWT, where "Darling I'm Home" is the time-honoured greeting, lawns are mown and cars washed on Sunday morning, and satirised by everyone from the Monkees to the Members. And Prince Albert's 1851 Great Exhibition, whose giant glass and iron hall was bought and moved there - by a railway company, as Britain's first theme park.
Why They're There: workers at the palace started their own team in 1861, but collapsed (the team not the palace) when some of them went off to form the FA two years later. They tried again in 1905 and survived, largely as they appointed Boro manager John Robson, who brought several players with him. Joined the League in 1920.
The Field of Dreams: The railways again. The willows had gone to the great cricket bat factory in the sky, and Selhurst was a brickworks owned by the Southern Railway until 1924, replacing The Nest, now the train depot next to Selhurst station. Like Molyneux, has built-in supermarket, useful when four goals down after an hour, or to stay alive on that long journey home.
When It All Began: November 1924, after Boro's first relegation and in Palace's third and last season in Div Two for 41 years. Only the ninth match played at Selhurst Park, with one stand unfinished after a builders' strike. Then on hold for another four decades.
Local Heroes: Johnny Byrne (England cap just after promotion from Division Four), John Salako, Vince Hilaire, Wright and Bright, Geoff Thomas, Nigel Martyn, Dean Gordon, Gareth Southgate, and (for a while) Terry Venables.
Local Villains: Millwall, and Charlton obviously; Itzhak Zohar, voted worst-ever foreign player after his Christmas 1997 penalty miss denied them a first home win until April; Michele Padovano, who Boro narrowly escaped signing, later jailed for drug smuggling; And Manchester United, who are to them what Chelsea are to Boro, especially at Wembley.
High Point: two FA Cup finals in 1990 and 2016, both beaten by Manchester United; finishing third in 1991; and now having a fourth season in the top division, something they've only done once before; four promotions to the Premier League.
Low Point: finishing bottom of Division Three South in 1951 (one of five times in nine years in its bottom four); four relegations from the Premier League after a single season.
Boro Highs: 3-1 (May 1968), the first win; it had taken 44 years. And the only one of the six there by more than one goal. 3-2 (September 1973) Charlton's Champions up and running.
Boro Lows: 2-5 (August 1980), after leading 2-1 at half-time; 1-4 (April 1993); 0-3 (September 1982).
Hello to: Colin Cooper (March 1986); Isaiah Osbourne and Marcus Bent (November 2009).
Goodbye to: Kris Boyd (February 2011).
Boro Hero: Craig Hignett (December 1992), only goal of the game, ending seven successive defeats there. No Boro player has ever scored twice there - and only one has at home, Arthur Horsfield in 1968.
End of an Era: 2-2 (November 1924), the last of George Elliott's 213 goals. 1-0 (April 2005), Boro were the last team to win a Premier League game there until Stoke eight years later.
Start of an Era: 3-2 (September 1973) John Hickton (2) and Brian Taylor's only Boro goal began a record 24-game unbeaten run.
Boro Bogeyman: Selhurst Park. Six wins in 93 years, three in the last 23 (and when Charlton and Wimbledon ground-shared there Boro won once against each in 14 visits) explained by just having to get there - the Crystal Maze. The endurance and spirit of Captain Cook through both searing heat and arctic bitterness clearly lives on in fellow Teessiders. There may not be cannibals or the Great Barrier Reef, but there are storms and plenty of (financial) sharks along the M25 or A232 through Beckenham. Don't even think about playing Count the Traffic Lights, as the will to live disappears after the first three dozen. There is of course a green alternative - but it's Southern Trains - check before travelling.
Mogga Bogeyman: Tony Mowbray played six Boro games there and lost the lot (and never won in four more with Ipswich); his first game in management was there (for West Brom); his first Boro win was against Palace at the Riverside, and after winning at last with Boro after nearly 20 years of trying in 2011 lost the next two - the last by 4-1.
Everybody's Bogeyman: Neil Warnock, whose 4-1 win in the last visit kept up his 100% home record against Boro, still going strong after 27 years, and last seen at Rotherham last March. Said this week that when he dies he wants a minute's booing at every club where they can't stand him.
Boro Bad Boy: Terry Cochrane, (December 1979), Joe Bennett (September 2011). But Boro won both with 10 men.
Typical Boro: 0-1 (November 2009 & February 2011), identical games of total Boro domination, identical missed sitters by Leroy Lita, then a sucker goal on the break.
Typical Computer: Easter 1969, the first time it was used, it sent Boro to promotion rivals Palace and Charlton on successive days while giving all the others in the top six two home games or a day off. They never won another game and went from second to fourth. Easter 1993, the M25 on Easter Monday, lost 4-1, bottom of the Premier League for the first time.
Four Seasons: Palace are the only team relegated from the Premier League four times, and the only one after finishing fourth-bottom (it was being reduced from 22 to 20 clubs in 1995); Four of Palace's promotions to the top division have been via the play offs, more than any other team.
Blame It On Boro: In 1905 The new Palace Pt. II hired the manager who'd taken Middlesbrough into the league, John Robson. When he left Boro after 17 years he got a gold watch, and his wife a silver dinner service. Palace took their colours from Aston Villa and half their team from Boro.
Omen Corner: this match is a year to the day since Ali Brownlee's funeral, which inspired the last Boro comeback at the Riverside, not to mention the fabulous goal they trailed to, scored by Fabio, then of Cardiff.
Your Boys Took One Hell of a Beating: Liam Neeson, Eddie Izzard, Bill Nighy, Timothy and Rafe Spall, Jo Brand ("I find it hard to get to the ground on matchdays as I can't get past Sainsburys"), Mark Steel ("all those millions on players would have been better spent buying a Rembrandt - and putting it on the pitch"), Paul Greengrass (for whom United 93 shouldn't be confused with United 90 or 06), Peter Davison (years of vet filming in North Yorkshire had no effect on him as Boro were at an all-time low then), Chuka Umuna (once sold tickets and trinkets in the club shop - but then his dad was a director), and after outing himself, handily just before the 2015 election, Nigel Farage. As several of the above might put it, he's on pretty safe ground with them when it comes to getting into Europe.
