A tower and a method of constructing a tower. The tower has three support members and an upper member. Each support member has an outside leg and two inside legs, laced together in a triangular cross section. The upper end of each inside leg is attached to the upper end of one of the other inside legs. The inside legs may also be connected at an intermediate point to form a window. An upper member, having three legs, laced together to form a triangular cross section, is erected on top of the support members, so that the legs of the upper member extend upward from the outside legs of the support members.
