Geocache Description:


09-06-2010: In de loop der jaren is de schrijfwijze van rekenopdrachten door de intrede van computers nogal veranderd. Ik heb in deze tekst mijn best gedaan om alle opdrachten om te zetten naar een hedendaagse schrijfwijze. Voor onduidelijkheden in het veld : ab = axb = a*b !


N.B.: dd. 22-07-2012 werd opdracht "Hoekje" aanzienlijk gewijzigd ==> gebruik "verse" uitdraai !

NB: je moet voor deze cache een KRUISPEILING kunnen maken !


Geocaching is een stiekeme hobby die alleen kan voortbestaan indien de deelnemers zich dit realiseren en zich er naar gedragen: !! WEES STIEKEM !!

The Castle-/ Kastelenseries consists of :

1. Bridge to Bridge GCHDTC
2. Heeswijk castle GCHE2J
3. Seldensate castle GCHE1H

And includes a BONUSCACHE:

4. Kersouwe GCHFWW



Inside the cachebox you will find an orange sticker containing information about the Kersouwe bonuscache!




There is not much left of the former Seldensate castle (+/- 1490) . Like most of these castles or mansions in the area Seldensate originates from the 15th century.

The area was a popular one because of the vicinity of the city of 's-Hertogenbosch.

The mansions were mostly lived in in summer and/or in times of the plague or disturbances and rebellion.  Most of them were abandoned after the "80-Years war/Tachtigjarige oorlog" which ended in 1648.

There must have been some 10 of these "speelhuizen" in the Berlicum area of wich only from the Wamberg ( => Bridge to Bridge, and Beyond : GCHDTC )and Seldensate visible signs are left.


Seldensate castle itself is no more than a ruin, but the gatehouse and pigeontower were kept (and partly restorated in 1980). This contained the entry/gate , a brewery , stables , guestquarters and the gatekeepersquarter.


Nowadays, Seldensate castle and it's park are open to pedestrians only.



The length of the route is approximately 2 km., but it will require much more time then you'd expect !

  • the number of steps from SW down onto the deepest tiled floor = E.(aantal treden/stappen vanuit ZW omlaag naar de laagste tegelvloer)


  • Do not go to "Hoekje" at: N = . C² + E² + 2*D - D/5        E = . 102*D + 4*E + 2*C anymore
  • here - at the left topside of the lowest "circle" - you had to locate a cannister containing next important information: A = G*X + (F/E)*(C + E) and B = D*Y + G + F - F/E


  • Go to : N 51 39.799   E 005 24.557 and find yourself nearby a huge fallen tree ( een grote, omgezaagde boom).
  • Locate the alu tag about halfway and on the westside of the trunk(alu plaatje halverwege de stam en aan de westzujde ervan): X = ..
