This thesis focuses on the study of accelerating solutions within the context of Einstein-AdS gravity in 2+1 dimensions, exploring both classical and holographic perspectives. These solutions exhibit a diverse range of phases that bear similarities to the C-metric in 3+1 dimensions while displaying certain peculiarities and novelties.

We start by describing the different classes of geometries that can be obtained from analysing the three-dimensional C-metric. After including a domain wall that acts as the external force driving the acceleration, we construct accelerating point particles and accelerating Ba\~nados--Teitelboim--Zanelli (BTZ) black holes exhibiting distinct accelerated phases depending on the energy density of the domain wall. Furthermore, we present a novel accelerating black hole that is not continuously connected with the BTZ black hole. A detailed description of the spacetimes and their embedding into AdS$_{3}$ is presented.

From there, we investigate the boundary description of such geometries with particular emphasis on the accelerating BTZ black holes.
We find that the Fefferman--Graham prescription developed for accelerating black holes in four--dimensions leads to a holographic stress tensor that depends on the conformal freedom of the boundary metric. While this behaviour is natural, computing holographic quantities requires choosing a particular conformal representative. As an alternative, we propose that using an Arnowitt--Deser--Misner (ADM) ``radial'' decomposition offers a more suitable identification of the boundary data. Our findings reveal that the dual conformal field theory lies in a curved background being characterised by the stress tensor of a perfect fluid.

The Euclidean action is also obtained ensuring a well-posed variational principle. This requires including contributions from the internal boundaries generated when including a domain wall to the spacetime. We show that these boundary terms can be expressed in terms of the Nambu--Goto action of the domain wall which is added on top of the standard renormalised Einstein--Hilbert action for AdS$_{3}$.

Finally, we compute the entanglement entropy by using the fact that the solution can be mapped to Rindler-AdS where the Ryu--Takayanagi surface is easily identifiable. As the acceleration increases the accessible region of the conformal boundary decreases and therefore the entanglement entropy also decreases. This is interpreted as a process in which the dual theory loses information due to the acceleration.
