Gates

The gates would be open and closed by redstone. Gates would be able to be able to be broken through by things like withers, wardens, iron golems (enraged at wardens and any boss mob only). When crafting the gate (I can't think of a crafting recipe but it would include iron blocks or iron bars) the player would have to use a 6x6 crafting table to craft the gate. There would be a variety of gates, such as a medieval gate and a strong gate like a SCP gate. The gates would open and close from any redstone activation method. There would also be gates that open inward/outward, basically big doors. These gates would also fit in with the ancient cities, like a broken up gate attacked by the warden. The gates would also make it so players don't have to spend so much time on command blocks to make a "unrealistic" gate. The gates would also make a moderately loud sound. The sounds would only remain until a day and half goes by, then the noise will not play. The gates would range from 7 to 16 blocks vertically and 7 to 20 horizontally. Gates aren't commonly mention but they would help alot. If seasons are added to Mincecraft the gates could freeze (ice only) and the ice would need to be removed (anyway works) to work again. Please take this into consideration.
