[1] In 1260 Peter II, Count of Savoy acquired the rights to what became the site of the town and castle of Yverdon.

It was planned out by the young mason and architect James of St. George as apprentice to his father Master John.

A few years later, Yverdon acquired the castle, to entrust it to Johann Heinrich Pestalozzi and his institute.

New classrooms were created, especially on the second floor: dividing walls were erected, additional windows changed the severe look of the castle's façade.

The castle is today a multi-purpose cultural centre, housing a regional museum, a theatre, various conference rooms and the oldest public library of French-speaking Switzerland, founded already in 1763.
