Abstract
In this note methods are developed which permit us to concretely calculate the hermitian Picard group of a congruence order A over a discrete valuation ring, with respect to an involution alpha of A. In particular, this allows us to exhibit some explicit examples of algebras A whose hermitian Picard group strongly depends upon the chosen involution on A.
