The CASTLE GATE

The Castle Gate defines the power of your castle wall and the general defensive possibilities. By upgrading the Castle gate, you can build additional defensive fortifications and extend the path an aggressor has to navigate to reach your Castle Gate.

Functions:

The Castle Gate is essentially the last line of defense against intruders. It protects the inner premises of the town and its buildings (e.g., Throne Room, Troop Academy, Wizard's Tower, etc.) and keeps about half of the Treasure Chamber's gold contents safe.

This structure determines the strength of the kingdom's overall outside defense. By upgrading it early, you can extend your path and erect more towers and traps to keep intruders from reaching the kingdom's entrance.

The Castle Gate has a 95% and 50% resistance to poison and piercing, respectively; however, it is 100% weak against blunt attack.

TIPS

It is critical to devote one worker for the upgrade of the Castle Gate so you can lengthen your path and add more towers and traps to destroy intruders before reaching the Gate. 

Though this structure has a 6.5 range (second longest to the Firebolt Tower's 7), it deals only a minimal damage. A Level 8 Castle Gate only deals 38 piercing damage compared to the 89 damage of a Level 5 Arrow Tower. So, it is best to place other towers nearby the Castle Gate to distract the enemies and prevent the attacker from gaining three stars and full loot.

To destroy the Castle Gate fast, spawn troops with blunt damage, such as Paladins and Cannons. 

How do you prevent your Castle Gate from being destroyed too fast?
