We show that the theory of General Relativity can be entirely formulated in the language of the integrable Weyl geometry. We develop the concept of Weyl frames and state the fact that they are completely equivalent as far as geodesic motion is concerned. In the case of General Relativity, we build an action that is manifestly invariant with respect to Weyl transformations. In this scenario, the gravitational field is described by a combination of both the metric and a geometrical scalar field. We illustrate this point by examining how distinct geometrical and physical pictures of the same phenomena may arise in different frames for the particular case of conformally flat spacetimes. Besides, we show that our choice of Weyl geometry for desc...
