“A ruin must be rightly situated, to be effective. This one could not have been better placed. It stands upon a commanding elevation, it is buried in green woods, there is no level ground about it, but, on the contrary, there are wooded terraces upon terraces, and one looks down through shining leaves into profound chasms and abysses where twilight reigns and the sun cannot intrude.” Mark Twain – ‘A Tramp Abroad’
Heidelberg has an iconic status as a centre of Germanic history and culture. In 1815, at the end of the Napoleonic wars, the Emperors of Austria and Russia and the King of Prussia formed the ‘Holy Alliance’ in Heidelberg and later in 1848, the year of revolutions, a German National Assembly was established here.
