Description
The Mounted Gun in Anno 1800 is one of the first harbour‑defence guns you can access, and you unlock it at the Worker level. For the best results, place it along the edge of your harbour, which allows it to reach farther out toward incoming threats.
However, a Mounted Gun in Anno 1800 is the weakest defensive option in the game. They have a slow attack speed and only a medium attack range. At longer distances, their damage drops sharply, making them far less effective against distant targets.
Overall, they offer basic early protection, but you’ll want to upgrade to stronger defences as soon as possible.
Improvements
In this section, we’ll look at the best ways to improve the efficiency of your Mounted Guns. To begin, we’ll focus on simple upgrades that help them perform better in the early game.
Next, we’ll look at how adding a Cannon Tower can strengthen your overall harbour defence. By combining both, you create a much more reliable defensive line that can handle stronger threats as your city grows.

This is a very basic layout that gives your island some initial protection. However, it won’t be strong enough on its own. To improve your defence, you’ll need to add more guns so your harbour can handle stronger or multiple threats.
Harbourmasters office
When you want to improve your Mounted Gun in Anno 1800, you can use the Harbourmaster’s Office. Just like the Trade Union or Town Hall, it works by placing items into its slots. Once items are added, any buildings within its range—including Mounted Guns —will receive the benefits those items provide.
In the next section, we’ll look at some of the best items you can use to boost the performance of your Mounted Guns.
| Item name | Effect | Rarity/notes |
|---|---|---|
| Gunner | +200 Hitpoints, | Common Expedition Bonus – +5 Force +15 Naval Power |
| Artillerywoman | +300% Self-Repair | Uncommon Expedition Bonus – +10 Force +25 Naval Power |
| Vasco’s Lieutenant | +600 Hit points, +15% Damage per shot | Rare Expedition Bonus – +15 Force +35 Naval Power |
| Colonel Barzagli | -75% Maintenance Cost, +20% Attack Speed | Epic Expedition Bonus – +20, Force +45 Naval Power |
| Field Marshall Matravers | Spirited (extra damage when low HP), +100% Self-Repair, Active Healing | Legendary Expedition Bonus – +25 Diplomacy +25 Force +55 Naval Power |
Layouts
In this section, we’ll look at effective layouts for placing a Mounted Gun in Anno 1800 and the support buildings that improve them. To start, the main goal is to position your guns near the edge of the harbour, where they can reach incoming threats as early as possible.
As you plan these layouts, make sure to leave gaps for your trading ships to pass through. Without these openings, your harbour can become blocked, slowing down trade and disrupting your economy.
By balancing defence and accessibility, you create a layout that protects your island while still keeping trade routes clear and efficient
Option 1
In this first layout, the Mounted Guns are placed right along the outer edge of the harbour area. By positioning them here, they can fire at incoming ships as early as possible.
As a result, this setup provides enough defence for the early game, giving your island basic protection while you work toward stronger fortifications.
In this layout, you can see the Mounted Guns actively defending the harbour from incoming attacks. At this stage of the game, having three guns is more than enough to keep your island safe.
In addition, there is still plenty of space for ships to reach your Trading Post, ensuring that your trade routes stay open and efficient.
Option 2
In this layout, you can see that we are now adding longer‑range guns to the setup. These are Cannon Towers and will reach much further into the sea. By including these, your island’s defence becomes much stronger, as they can hit enemy ships before they get close to your coastline.
In addition, this layout also includes a Harbourmaster’s Office, which allows you to add items that further improve your guns. With these upgrades, your harbour becomes far more effective at stopping early‑game threats.
In this layout, you can see how the guns and towers are positioned around the harbour. Because of this placement, ships can continue to trade on the island without any obstruction.
As a result, you maintain strong defence while still keeping your trade routes open and efficient.
