Got it! ... I think ... thanks to the trusty Wikipedia. I think it is 'Port Murman', also known as 'Romanov-on-Murman', and eventually Murmansk.
On June 29 [O.S. July 12], 1916, Russian Transport Minister Alexander Trepov petitioned to grant urban status to the railway settlement. On July 6 [O.S. July 19], 1916, the petition was approved, and the town was named Romanov-on-Murman (Рома́нов-на-Му́рмане, Romanov-na-Murmane), after the royal Russian dynasty of Romanovs. On September 21 [O.S. October 4], 1916, the official ceremony was performed, and the date is now considered the official date of the city's foundation. After the February Revolution of 1917, on April 3 [O.S. April 16], 1917, the town was given its present name.
