The real estate arm of Boston-based Fidelity Investments is putting four Boston office properties and a small land parcel in the city’s Financial District on the shopping block. 

The contiguous block of assets totals 343,000 square feet of space and includes 82 and 68 Devonshire St., 19 and 15 Congress St., and the land parcel at 54 Devonshire St.

The package deal from Fidelity Real Estate Co. is being touted as a potential redevelopment site to incorporate the open land, currently a fenced-in area with small bushes, by CB Richard Ellis, the brokerage firm marketing the deal.

CBRE’s marketing materials cite examples of the "revitalization" of Boston’s Financial District through recent deals for companies like eBay, Converse, Partners Healthcare and legal firm Brown Brothers Harriman to locate or keep offices in the Financial District.

But there’s still a demolition site on Washington Street known as the old Filene’s building, and the hole in the ground remains a dark reminder of a major project gone wrong in what was once the retail heart of the city.

"Given the revitalization that is currently taking place in the Financial District with the influx of new companies and developments, we believe The Block on Congress site has extraordinary potential and flexibility that will attract interest from number of investors and developers locally and globally," Fidelity spokesperson Vin Loporchio said in a statement.
