Sumario:A total of 20 measurements carried out by the ATLAS and CMS Collaborations of the properties of top quarks were presented. These were measurements of the top quark charge, of the spin correlation between the top and the anti-top quark, of the charge asymmetry, of the polarisation of the W-boson, the measurement of the hadronic activity in the central rapidity region in $t\bar{t}$ events, and the measurement of the branching ratio of top quarks. Some direct searches for new physics were also presented: searches for fourth generation top-like and bottom-like quarks as well as more exotic $T$ quarks with anomalous decay modes.
