Global Seed Vault - Svalbard

The Svalbard Global Seed Vault, known as the "Doomsday Vault," is such a unique facility tucked away in the Arctic archipelago of Svalbard, Norway. Its mission - to protect and preserve the genetic diversity of the world's food crops. Its a vital backup facility housing millions of seed samples collected from across the globe.

TL;DR

In this post, we will dive into its location, construction, specifications, access, and current seed inventory, highlighting why this facility is crucial for future food security.

Location

Located 1300km from the North Pole, just outside of Longyearbyen, Svalbard, Norway. Difficult to walk to and better visited under the added protection of a tour.

The environment this far north is COLD, with low humidity. The region is geologically stable with permafrost.

We walked up an unassuming path from the minibus, cresting the hill to see the entrance- festooned with an art installation called “Perpetual Repercussion”, which reflects the Arctic light. Beyond that there isn't a lot to see, and you find yourself marvelling at the view of the harsh environment where this important building has been sited. In fact many deliveries will arrive via dog sled or snowmobile.

Who Built It and When

Construction began, ignore the stories that an old coal mine was used, in 2006. It cost the equivalent of 50 million NOK to complete, funded by Norway. The seed vault was inaugurated on February 26, 2008, as a collaborative project among the Norwegian government, the Global Crop Diversity Trust (Crop Trust), and the Food and Agriculture Organization (FAO) of the United Nations.

Who Manages the Vault

The contents of the vault are managed by NordGen - taking care of seed deposit logistics, documentation, and coordination with gene banks. The facility itself is managed by Statsbygg, the public sector administration enterprise responsible for government buildings. It has a permanent office in Longyearbyen and operates remote surveillance and monitoring systems to protect the vault and its contents.

Annual run costs are difficult to identify - but have been reported as around 12 million NOK

Technical Specifications

Built to endure natural disasters, climate change, and other threats.

The Svalbard Global Seed Vault is an engineering marvel. Built into a mountainside, it offers protection from external dangers and effectively maintains the temperature and humidity essential for long-term seed preservation. Here are key technical features:

• Depth: The entrance to the vault is approximately 120 meters into the solid rock of the mountain side, offering natural insulation and at 130m above sea level protection against rising sea levels, which is vital as climate change progresses.

• Structure: Blast-proof doors protect the main cathedral chamber, and three separate chambers, each capable are situated off the main chamber.

  
  

• Temperature Control: Consistently maintained at a chilling -18 degrees Celsius (0 degrees Fahrenheit), this controlled environment helps ensure the seeds remain viable for decades, and often for hundreds of years. If electric power should fail - seeds will remain frozen thanks to the permafrost.

  
  

How Is It Accessed?

Well - you aren't getting in, but there is an absolutely fantastic virtual tour is available here - https://www.seedvault.no/for-the-general-public/

The Seed Vault receives seeds three times a year, although it can set up special openings when situations call for it.

Access to the Svalbard Global Seed Vault is strictly regulated to maintain the integrity and security of the seeds. Entry is limited to a select group of personnel such as designated staff from the Nordic Genetic Resource Center, the Crop Trust, and trusted stakeholders.

Svalbard's Purpose

Svalbard is a fail-safe backup. Many other seed banks around the world store seeds for active use in breeding, research, and distribution. Svalbard's seed back is a vault or safety deposit box that does not distribute seeds - it only stores duplicate samples already preserved elsewhere.

A seed such as wheat or barley should remain viable if kept at Svalbard's ideal temperature some 2,000 years.

Deposits and Withdrawals

Accepts seed deposits from all countries and institutions, regardless of politics or affiliations.

As of August 2025, over 129 nations have contributed, 6,378 speciies and 1,356,591 seed samples according to its website - https://www.seedvault.no

Each seed sample is approx 500 seeds, and with room for 4.5 million seed samples - there is the potential for 2.25 billion seeds to be safely kept. If those seeds were lined head to tail - god only knows how far they would stretch.

Seeds are sealed in three-ply foil packages at source and stored inside sealed boxes on shelves.

Like a safety deposit box at a bank - each depositor retains ownership and control of their seeds, and only the original depositor can access their seeds.

The First ever withdrawal was in 2015 by ICARDA, whose seed bank in Syria was compromised during the war. They later re-deposited seeds after relocating their operations to Morocco and Lebanon.

Technical Upgrade

In October 2016, water encroached 15 meters into the tunnel before freezing. There was no immediate threat to the seeds. The vault's design and location within the mountain, combined with the extreme cold, ensured the seeds themselves remained safely stored. As a result a 200 million NOK technical upgrade was undertaken. The entrance tunnel was waterproofed. Cooling systems were upgraded and moved to a new service building to reduce heat generated within the tunnel. Lastly drainage ditches were constructed to divert meltwater away from the entrance.

This was widely reported by the press and served as a wake-up call regarding the impact of climate change.

The Importance of the Svalbard Seed Vault

Its remote location, advanced construction, and strict access controls make it one of the safest seed storage facilities on the planet. As challenges such as climate change, food supply issues, and population growth loom larger, the significance of the Svalbard Global Seed Vault will only increase.
