Market Church of the Holy Spirit, Clausthal-Zellerfeld

Highlight • Religious Site

Surprisingly large and very eye-catching church due to the blue color.

—-

Market Church of the Holy Spirit
The market church of the Holy Spirit in Clausthal was built in the middle of the Thirty Years' War from oak and spruce and the roof was covered with lead. In 1642 it was consecrated at Pentecost. The Market Church is the second largest preserved wooden church in Europe after Kerimäki Church. A very extensive renovation was completed in 2011.

Old Innerstetal Railway Line

Highlight (Segment) • Cycleway

The old railway line is excellent to drive. However, there are few turns to reach or leave the route on the way.

Hausherzberger Pond (Bathing Lake)

Highlight • Lake

Here you can jump into the water for free during your tour. By the way, bathing is permitted in almost all of the 60 ponds around Clausthal-Zellerfeld, unless it is expressly forbidden by signs.

Lautenthal

Highlight • Settlement

The mining town of Lautenthal owes its existence to a miner named Kaspar Bitter, who discovered a rich ore vein on the Kranichsberg around 1530. With some of the silver ore he had found, he went to the then sovereign, who paid him handsomely and prompted him to start mining in the valley of the lute. Three and a half centuries passed, during which every man in the village was connected with the mining industry, its changing ups and downs, its rare times of prosperity and frequent times of need, for better or for worse. Most of the mines ceased operations in 1930/31.
Today a state-recognized climatic health resort in the middle of the Harz Nature Park

Innerste Dam

Highlight • Lake

The Innerste Dam is a dam in the Innerste region, located in the northwest of the Harz Mountains between Langelsheim, Wolfshagen, and Lautenthal. It was built between 1963 and 1966 and belongs to the Harz Waterworks. Its purposes are drinking water supply, flood protection, low-water elevation, and power generation. The average annual discharge of the Innerste Dam is 60 million cubic meters.

Innerste Cycle Path

Highlight • Cycleway

For me, the Innerster Cycle Path between Wildemann and Langelsheim is one of the most beautiful cycle paths in the Goslar district. It doesn't run directly along the road, even though it's right next to it for most of its stretch. However, since it runs along the former railway line, the path is secluded enough and lined with trees to allow you to cycle through beautiful nature.

Innerste Reservoir

Highlight • Lake

Structures

The dam of the Innerste Dam is an earth dam with a multi-layered, external asphalt concrete seal. It has an inspection passage in the water-side hearth wall along its entire length. In front of the water-side foot of the dam there is a flood overflow tower, into which the bottom outlet is also integrated. The water from the Innerste Dam can be pumped via a 4.6 km long pressure pipe to the Grane Dam to the east, where it can be used to treat drinking water. From 2003 to 2005 the dam was completely drained and the asphalt seal and bottom outlet in particular were renovated; the construction work was completed in September 2005.

Day 3: Weather-wise, today was another great day. In bright sunshine today we set off from Osterode towards the Sösestausee.
However, the cycle path is closed, what now? Or a huge detour?
However, if you look closely you can see a lot of tire tracks, so go through.
It was worth it, because the closure no longer had any basis, …

The route I have driven here deviates from the Weser-Harz-Heide cycle path in order to reach two nearby stamping points. Mandolinenhütte (142) and Morgenbrodstaler Graben (146).

After the train service thwarted my plans on Ascension Day, I rode the second stage on Friday. I'll make up for the first stage later.
Starting at the campsite in Scharzfels, I first had to cycle to Herzberg am Harz.
From there, I first cycled along a country road …

July 3, 2024,Weser-Harz-Heide-Radweg - Tag 3 - Osterode am Harz nach Goslar

The tour of suffering and dams was quite pleasant for the first 10 km to Riefensbeek-Kamschlacken (what a place name) along the Sösetalsperre, but then the Harz announced itself with a never-ending, torturous climb (no e-bike!) to Clausthal-Zellerfeld.

Just behind CLZ, the Bockswieser Höhe was the highest elevation of the stage and the entire tour at 610m above sea level.
