A form for manufacturing concrete blocks for constructing freestanding
walls. The form includes a base and four side panels which are mounted on
the base to pivot between a first position for casting a block and a
second position for removing a cast block from the form. An insert is
secured to the base for forming one end surface on the block and inserts
are attached to the side panels for forming sides, top and bottom surfaces
of the block. The inserts which form exposed sides of the block are
textured to simulate natural stone. The inserts which form the top and
bottom of the blocks form an interlocking connection which prevents
stacked blocks from moving in a horizontal plane. Optionally, inserts used
to form the top surface of blocks which will define the top of the wall
may form a trough which is sufficiently deep to receive soil and plants.
