The Gutenberg Museum in Mainz is full of interesting exhibits about the history of printing. It has an amazing collection of printed material from the 15th century onwards including two copies of the Gutenberg Bible, which was the first major book printed in Europe using movable type.
There is also a section on the history of printing in China from the 8th century and printing in Islamic countries.
But perhaps the most interesting part of the museum is Johannes Gutenberg’s reconstructed workshop. Here museum guides show how printing was done during Gutenberg’s time. The demonstrations take place every hour, on the hour from 10am to 4pm. You can ask at the front desk if any of the talks will be in English.
On the pavement outside of the museum, cubed sculptures feature typefaces of different kinds.
