In Nikko, near the Sanbutsu-doh Hall from the Rinno-ji Temple (photos), you can see the Sohrintoh Tower, a bronze tower built in 1643 by the priest Tenkai.
1000 volumes of Buddhist Holy Scriptures are stored under this tower, and on the 13.2-meter tall tower, decorated with 24 bells, we can see engraved the mon (crest) of the Tokugawa family, 3 hollyhocks:
Sohrintoh Tower was initially built at the Toshougu Shrine (photo) and in 1650 it was moved near the Futarasan Shrine (photo). In 1875, after the Meiji law regarding the separation of Shinto Shrines and Buddhist Temples, it was moved again, on its current location.
I think that in the past it was more spectacular, but today it looks cold and dull, the bronze is oxidized, greenish, and the 24 bells aren’t shining anymore.
Another interesting object, right near the tower, is a lantern, Itowappu Tourou, donated by the local population as thanks to Tokugawa Ieyasu for the privilege of silk trading (Itowappu was the permission to trade silk).
