This note is based on the lectures that I have given during the winter school Winter Braids IV, School on algebraic and topological aspects of braid groups held in Dijon on 10 - 13 February 2014. The aim of series of three lectures was to give an overview of geometrical and topological properties of 4-dimensional Lefschetz fibrations. Meanwhile, I could briefly introduce real Lefschetz fibrations, fibrations which have certain symmetry, and could present some interesting features of them.This note will be yet another survey article on Lefschetz fibrations. There are excellent lecture notes/ survey papers/ book chapters on Lefschetz fibrations. You can, for example, look at [3], [11], [14], [20] among many others. In this note I intent to take my time on real Lefschetz fibrations as much as on Lefschetz fibrations in order not to repeat what was already done perfectly.
