Najosjetljiviji dio burga bio je ulaz, pa se o njemu vodila posebna briga. Ulaz je bio nad terenom ili je kopan jarak pred njim, a ulazilo se preko mosta koji je u jednom svom dijelu bio pokretan. Ulaz je štićen s vrha zidina odnosno s branič--kule ili je pak bila izvedena posebna ulazna kula. Pokretni su mostovi dizani lancem ili drvenim polugama. Ulaz je zatvaran drvenim zaokretnim krilima i okomito posmičnom rešetkom. Do danas je ostalo sačuvano vrlo malo ulaza, a od opreme ulaza - pokretnih mostova, vratnih krila i sl., nije ostalo gotovo ništa.The most vulnerable part of a burg was its gate, and special attention was paid to it. The gate was placed on higher ground or fronted by a ditch and approached across a drawbridge. It was guarded from the walls or the keep, or had a special gatehouse. Chains or wooden levers were used to raise the drawbridge, and a hinged wooden door and portcullis closed the entrance. Very few gates have been preserved, and almost no drawbridges, doors and so on
