Anenský vrch, Mountain summit in Hradec Králové Region, Czech Republic

Ernestinenberg, also called Anenský vrch, is a summit on the main ridge of the Orlické hory in the Královéhradecký kraj, in the Deštenská hornatina and its Anenský hřbet sub-unit. The bare ridge top holds two Czechoslovak infantry blockhouses, R-S 84 "Arnošt" and R-S 85 "Anna", and a 17-metre wooden lookout tower called Anna.

A chapel of St. Anne stood on the summit from 1760; it was rebuilt in 1820 and 1860, then dismantled in 1937 and moved to the settlement of Hadinec. That same year two Czechoslovak infantry blockhouses, R-S 84 "Arnošt" and R-S 85 "Anna", were built on the peak, and a Marian column was removed because of their construction. The column was restored and returned to the summit in 2024.

The name recalls the chapel of St. Anne that stood on the summit from 1760 until 1937, when it was dismantled and moved above the settlement of Hadinec. The peak was formerly called Arnoštka, in German Ernestinenberg, and the wooden lookout tower built in October 2010 is named Anna after the same saint.

The summit is reached by a roughly 400-metre red-marked spur off the Jirásek Trail from the Anenský vrch signpost, where the blue trail from Říčky also passes. The main ridge route continues to neighbouring peaks, so plan the return before setting out.

Multiple footpaths converge at this peak, which local hikers use to move between neighboring summits in the highlands. This makes the mountain a natural junction point along several connected routes in the region.
