A symmetric design is called {it symmetrically decomposable} if its incidence matrix can be decomposed into blocks with each block being a zero matrix or an incidence matrix of a smaller symmetric design. The existence of such designs and a few related objects such as Balanced Generalized Weighing matrices and Bush-type Hadamard matrices will be discussed.
