this is how you lock a gate
all across england and wales, there are public footpaths that are available for walking. i felt strange at first walking across someone's meadow where sheep are eating grass just meters away, but people have even built steps to help you over fences and walls that you might come across during your walk. these footpaths only apply to walkers (and "bridleways" that also allow cyclists and people on horseback), but i was still surprised to see this heavily-locked gate as we walked through the lake district in northwest england!

How does that even work? Is it like launching nuclear missles or an apartment building mailbox bank? (i.e. Does everyone have to be there smiultaneously in order to open the gate, or does everyone's key basically do the same thing?)

This is so quirky :). Couldn't help but put it on my facebook page...
Very clever design, unlocking any single padlock will open the gate.
Designed for several people to each fit their own lock & look after their own key.
There's vertical versions available too.
Yes I googled it :)
What StuntTrader said. Of course, as that first padlock is unlocked, the whole impressive device may as well not be there.
I've seen similar on places where there are a lot of different companies which need access. E.g., a fenced-off area near High Wycombe which is primarily a water pumping station but also has cell phone and other (emergency services?) towers. There they use the even lower-tech solution which is to just form a chain out of the padlocks.
In theory you could implement simple logic with series/parallel arrangements: e.g., access is allowed if the land owner or his farm manager is present and so is one person from either the water company or the electricity company.
