The 1869
Macoupin
County Jail
The historic 1869 Macoupin
County Jail was also
designed by E.E. Meyers.
It was built using the
"cannon ball" method which
prevented jail breaks by
making it nearly impossible
to remove the blocks. This
unique medieval-inspired
fortress housed many
lawbreakers during its 119
years of use, but only one
prisoner escaped. He was
soon apprehended a few
blocks from the jail.

The interior is designed in
the "jailer residence" style,
a popular 19th century
prison design, requiring the
jailer and his family to
reside in an apartment
above the jail. The cell
block ceiling, walls and
floor are constructed of
one-inch iron plates with 20
inches of solid stone above
and below. The jail was
built to house 16 male
prisoners and one female,
but at one time it held 33
prisoners, four of whom
were accused murderers.
This historic structure was
finally retired when the new
county jail was built and
dedicated in 1988.
