I'm just back from the new must-see destination in Europe.
Entry costs a more modest €8 and once you're inside the crazily styled, 35,000 tonne edifice, you'll have 5.5 square kilometres of Porsches to look at.
Actually, there aren't that many cars on show at any one time - about 80 of the 400 owned by Porsche to ensure a frequent turnover for returning visitors - but what cars they are.
They don't just have a 917 here, they have eight 917s. And not just customer cars, but the most important of all: the 1971 Le Mans winner, the 1100bhp 917/30 that won every round of the 1973 CanAm championship, Pedro Rodriguez' classic Gulf-coloured 917K and even the 917PA Spyder with the fabled but never raced 880bhp air-cooled flat-16 motor in the back. It is a never-ending assault of immortal numbers: 904, 908, 909, 935, 936, 956, 961 and 962C to name just a few of those I scraped my chin walking past.
But it's the oddities I found equally interesting, not least because there are many there I didn't even know existed. There's the 1959 Type 754 prototype from which the 911 was born, a long wheelbase 911S from 1970, and a four door 928S which, had it made production, would have done precisely the job Porsche now intends for the Panamera.
