1844 marks the beginning of monument preservation and rescuing of the Allerheiligen Monastery ruins. The later state inspector of ancient monuments, August von Bayer, ordered measured drawings of the monastery to be prepared and restored the remains of the church. Initial excavations by Wingenroth and Statsmann followed in 1902-1903.
The ruins also received a decisive impulse for attention to monument preservation from the development of the waterfalls beginning in 1840 by the forest-keeper Mittermaier, who also ran the first inn in the upper Lierbach valley. The "romantic" monastery ruins and the surrounding area were often painted and sketched often in the time that followed. The resulting prints were very popular and attracted many visitors. These included Karl Baedeker, who added Allerheiligen to his travel guide in 1854, and the American author Mark Twain. In his book "A Tramp Abroad", this European traveler wrote a delightful account of Allerheiligen in 1878:
"The entire afternoon we had wandered uphill. Toward five or five-thirty we reached the peak, and suddenly the thick curtain of forest parted and we looked down into a deep, magnificent valley and far beyond tree-covered mountains with peaks that glistened in the sun, while their jagged slopes were softened by violet shadows. The narrow valley at our feet - it was called Allerheiligen - offered just enough room at the end of its grassy bottom for a cozy, blissful human nest, unreachable by the world with its burdens (...)
The "Schwarzwaldverein" (Black Forest Association) connected Allerheiligen in 1879 with its network of trails and placed the war memorial of the Badischer Schwarzwaldverein (Baden Chapter of the Black Forest Association) above the waterfalls in 1925. Today over 250,000 visitors still climb the idyllic waterfalls every year.
