Guardhouse by Peterbourgsky outpost, Veliky Novgorod, Regional cultural heritage site in Veliky Novgorod, Russia.

The surviving guardhouse of the Peterbourgsky outpost stands on Bolshaya Sankt-Peterburgskaya Street in Veliky Novgorod. Its north and south facades are identical: a central arched niche framed by two Doric pilasters with a window between them, a relief of Novgorod's coat of arms above, and a triangular pediment whose tympanum carries a high relief of the double-headed eagle with the monogram of Nicholas I. The west facade facing the road holds the main entrance in a semicircular loggia on two Doric columns.

The outposts at Novgorod's Moscow, St Petersburg and Pskov approaches followed the town plan approved on 16 June 1778 under Catherine II's 1763 decree on urban plans. The two stone guard buildings on the St Petersburg road were rebuilt in 1834 to a project signed by Major-General F. I. Röhrberg, found in RGVIA archives. Only one of the pair survives.

The building carries the coat of arms of Novgorod in a bas-relief above its arched niche and the monogram of Nicholas I on the double-headed eagle of its pediments. In late May to early July 2017 it housed the election campaign office of opposition politician Alexei Navalny.

The surviving guardhouse stands on the west side of Bolshaya Sankt-Peterburgskaya Street, in the Okolny Gorod line. Its main entrance faces the old road, under a semicircular two-column Doric loggia. The building is a regional cultural heritage site; no regular opening hours or guided tours are documented.

Only one of the two guardhouses survives; the other was lost, and the iron fence with lamp posts and the barrier that once stood between them are gone too. In 1834 the rebuilt facades were signed by Major General F. I. Röhrberg, though G. K. Lukomsky had earlier attributed the design to K. I. Rossi.
