Adlerstein (676 m a.s.l.) is a quiet but rewarding summit in the central Saxon Ore Mountains, near the town of Pockau-Lengefeld. It may not be the tallest peak in the region, but it comes with a genuine piece of surveying history right at the top — and on a clear day, the views stretch all the way into the Czech Republic.

The hill sits in the forested heart of the Middle Erzgebirge, close to federal road B101 between Heinzebank and Pockau. At its foot lies the well-known Lengefeld limestone quarry, giving the surroundings a distinctive mix of natural and industrial character. The panorama from the top — though partly grown over by trees — includes the Saydaer and Brander heights, the town of Marienberg, the Pöhlberg, and across the border: Jelení hora, Hora Svaté Kateřiny and Čihadlo in the Czech Republic. For the best views, the Adlerstein pairs nicely with nearby Lauterbacher Knochen, the two summits complementing each other's vantage points. Autumn is a particularly beautiful time to visit, when the surrounding forests glow with colour.

• Pockau-Lengefeld (roadside parking near B101) — no marked trail noted in sources; the ascent is short and easy.

• The summit features triangulation pillar No. 87 of the Royal Saxon Triangulation, erected around 1870 as part of the official land survey of Saxony.
• Views from the top are partially obstructed by tree growth.

That modest stone pillar on the summit is no ordinary marker — it is one of the surviving geodetic reference points from the great Saxon land survey of the 1870s, a small but tangible piece of cartographic history.
