European data center firm Data4 has broken ground on a new campus outside Athens, Greece.

“We’re excited to announce that today, Data4 Group laid the first stone of its brand-new data center campus in Paiania, East Attica, Greece,” the company posted on LinkedIn this week. “This marks a significant milestone in our European expansion, and we were honored to have Greece’s Prime Minister Kyriakos Mitsotakis, along with several distinguished guests, join us for this special occasion.”

The company announced plans for a 90MW campus in September. The €300 million ($331m) AT1 site is sat on 7.5 hectares. The first of the two buildings is due to go live in early 2027.

“We are now a foreign investment-friendly country. This is something that is proven not only by Data4's investment, but overall by the increased number of investments launched in our country,” Prime Minister Mitsotakis said.

Established in 2006 by Colony Capital (now DigitalBridge) and owned by Brookfield since April 2023, Data4 currently operates around 30 data centers in France, Italy, Spain, Poland, and Luxembourg. The company is also developing a former army barracks in Hanau, Germany, that could reach 200,000 sqm (2.1 million sq ft) and 180MW, and is planning a new campus in Milan, Italy.

Brookfield acquired Data4 from Axa IM – the deal was said to be valued at around $3.8 billion. Brookfield Infrastructure Partners is reportedly weighing a minority stake sale in some of the assets of French Data4.

Colo firms Sparkle and Digital Realty operate data centers around Athens.
