What was the name of the monastery where Gregor Mendel conducted his pea plant experiments?

Gregor Mendel conducted his pea-plant experiments at St. Thomas Monastery in Brno.

The institution is more commonly called St. Thomas's Abbey, or the Augustinian Abbey of St. Thomas. Mendel entered the Augustinian order in Brno in 1843, partly because monastic life provided him with a route to education and a stable livelihood. He later became abbot of the monastery in 1868.

Between 1856 and 1863, Mendel cultivated and studied pea plants in the monastery’s experimental garden. He selected seven characteristics, including seed shape, seed colour, flower colour, pod shape, flower position and plant height. By carefully controlling crosses and counting the results across generations, he identified predictable patterns of inheritance.

Mendel presented his findings to the Natural History Society of Brno in 1865 and published them in 1866. The work attracted little attention at first, but researchers rediscovered its importance around 1900. The monastery garden remains closely associated with the beginnings of genetics.
