  The Large Hadron Collider (LHC) was operated at a center-of-mass energy of
$\sqrt{s}$ = 7 and 8TeV for proton-proton collisions in Run I. The CMS and
ATLAS detectors both collected approximately 20 $fb^{-1}$ of 8TeV data in the
data taking period. This large dataset collected at an unprecedented energy
provides an ideal opportunity to search for new physics. In this paper, a
selection of recent results from the ATLAS and CMS Collaborations concerning
searches for exotic phenomena are presented. The signal models of these
analyses contain heavy resonances, dark matter particles, and long-lived
particles.
