From October 1914 until October 1918 the battlefield was barely a few kilometres away from the centre. The trenches had been dug from North to South to form an arch around Ypres. In that famous Ypres Salient no fewer than five bloody battles were fought.
In the nineteen twenties more than 150 military cemeteries were built in and around the city and monuments were erected. Menin Gate being the most important.
