A new black hole solution in 2+1 dimensions is found by taking cosmic strings as part of the vacuum structure of the anti{endash}de Sitter space-time. The solution has a structure that in many ways is similar to that of the Reissner-Nordstroem solution. With a vanishing cosmological constant, a space-time with a black hole of infinite extension appears with the inner horizon playing the role of a cosmological event horizon. The timelike and null geodesics are discussed. In particular it is shown that photons may follow conic sections. {copyright} {ital 1997} {ital The American Physical Society}
