  The top quark is the heaviest known elementary particle and plays a special
role in the dynamics of fundamental interactions. Since its discovery at the
Tevatron, several of its properties have been measured by the Tevatron
experiments (CDF and DZERO). However, thanks to its unprecedentedly large
production rate at the LHC a new level of precision in these measurements has
been achieved by the LHC experiments (ATLAS and CMS). The latest LHC
measurements of the top quark mass, total decay width, top-antitop spin
correlations, and charge asymmetry are presented in this contribution. In
addition, the results from the W-boson helicity measurement are presented.
