Geocache Description:


SK:

V rokoch 1935-1938 prebehlo budovanie najrozsiahlejsej a najnakladnejsej stavby v historii prvej ceskoslovenskej republiky. Tisice objektov opevnenia bolo vybudovanych v pohranicnych oblastiach ako obrana proti hrozbe zo strany nacistickeho Nemecka, ale aj inych susednych statov, s ktorymi mala republika napate vztahy. Do roku 1951 bolo planovane opevnit celu hranicu, okrem 200 km useku hranice s Rumunskom, ktore bolo povazovane za spojenca. Okrem toho mali byt opevnene aj strategicke vnutrozemske priecky. Vystavba vsak bola nahle ukoncena v septembri 1938 po podpisani mnichovskej zmluvy.

Opevnenie bolo budovane podla vzoru francuzskej Maginotovej linie. Pozostavalo z tazkych a lahkych objektov. Tazke objekty zahrnali pechotne zruby a delostrelecke pevnosti. Zakladom tazkeho opevnenia bola linia pechotnych zrubov, vyuzivajucich system bocnych, vzajomne sa prekryvajucich palieb. Zo strany nepriatela bol zrub zasypany zeminou, nebola teda odkryta ziadna strielna. Priestor medzi objektami opevnenia bol vyplneny protitankovymi a protipechotnymi prekazkami.

Povodny rozpocet na vystavbu opevnenia bol 10,9 mld korun ceskoslovenskych. Z tejto sumy sa do ukoncenia vystavby stihla preinvestovat asi stvrtina. Po ukonceni vystavby ostali rozostavane useky v roznom stave. Tazke opevnenie pravej strany Dunaja bolo v tejto dobe prakticky dokoncene. Pocas vojny sa cele toto uzemie dostalo pod nadvladu Nemecka. Napriek tomu zruby neboli znicene, tak ako na niektorych inych miestach.

Na petrzalskom uzemi bolo povodne postavenych 15 pechotnych zrubov, z ktorych sa dodnes zachovalo 12. Ostatne boli znicene pri vystavbe petrzalskeho sidliska. Okrem toho existovali 4 velitelske objekty a niekolko dalsich doplnkovych stavieb. Stages tejto multikesky vas zavedu ku vsetkym dvanastim existujucim zrubom bojovej linie.

Nezabudnite si so sebou zobrat meter. Budete ho potrebovat.

Necakajte od stages tejto kesky oku lahodiace miesta. V skutocnosti je tam casto hromada odpadkov a niekedy sa tam zdrziavaju bezdomovci alebo ine zivly. Preto nehladajte v noci a ak by to malo byt nebezpecne, radsej napiste alebo zavolajte kvoli niektorej indicii priatelovi na telefone.

Ak budete hladat v mokrom obdobi, ratajte s tym, ze domov sa vratite dvakrat tazsi nez ste odisli - rozdiel bude sposobeny nalepenym bahnom. Takze neodporucam na hladanie biele lanove nohavice.

A ak by niekto este nemal bunkrov plne zuby, je tu aj pokracovanie.

OCHRANA PRIRODY: Stages 1, 2, 3, 4, 10, 12 a final sa nachadzaju v oblastiach, kde sa chrani priroda. Prosim nepokusajte sa v tychto miestach o drive-in. Specialne to plati pre poslednu stage a final, ktore sa nachadzaju v rezervacii s 5. stupnom ochrany.

Stage1 B-S-1 "Sterkoviste"

Zajdite asi 2m dovnutra objektu a vsimnite si na pravej stene cervene graffiti tanku. Pocet jeho viditelnych kolies je A.

Stage2 B-S-2 "Mulda"

Vylezte na strechu ku pravemu pancierovemu zvonu. Odmerajte priemer otvoru na jeho vrchu. Priemer = B cm.

Stage3 B-S-3 "Paseka"

Zmerajte sirku strielne hned pri vchodovych dverach. Zaujima nas sirka pri usti (v najsirsom mieste). Zaokruhlite na desiatky cm. Sirka = C cm.

Stage4 B-S-4 "Lany"

Zrub je momentalne rekonstruovany. Tunajsia partia ma aj webovu stranku. Na lavej strane objektu je velka zakrytovana strielna pre protitankovy kanon. Spocitajte vsetky hlavicky skrutiek, viditelne na strielni a bezprostredne pod nou. Vysledok je D.

Stage5 B-S-6 "Vrba"

Tuto indiciu najlahsie ziskate ked sa vystverate na strechu objektu. Zamerajte sa na stenu, v ktorej su aj vchodove dvere. Z vrchu tejto steny trci E kovovych ok. Okrem toho tam boli 2 dalsie oka, ktore su uz odlomene. Na tomto bunkri aktuálne prebiehajú úpravy, takže dočasne E = 4.

Stage6 B-S-7 "Cviciste"

Tato stage je uprostred pola. Vzhladom k tomu, ze po vacsiu cast roka je nepristupna kvoli nepriechodnemu blatu alebo porastu kukurice, je navsteva dobrovolna. V okoli je aj viacero zaujimavych objektov protitankovych stien a murovanej makety tanku.

Stage7 B-S-8 "Hrbitov"

Tento zrub sa zacina prebudzat k zivotu. Od jari 2009 ho rekonstruuje partia nadsencov pod vedenim p. Kosirera. Okrem moznosti prejst sa vo vnutri a dostat odborny vyklad su tu vystavene dobove vojenske fotografie a predmety a obcas sa poriadaju specialne akcie pre verejnost. Blizsie info TU alebo TU. K indicii sa kusok musite prejst ku zrekonstruovanemu vojenskemu cintorinu z 1. svetovej vojny. Kovova vstupna brana do cintorina je zdobena viacerymi 10 cm dlhymi horizontalnymi kovovymi tyckami. Spocitajte vsetky, pripocitajte jednu chybajucu, a dostanete okruhle cislo F.

Stage8 B-S-9 "Kittsee"

Aj o tento objekt prejavila zaujem partia nadsencov a od jari 2010 ho skulturnuje. Mala vstupna miestnost bunkra ma dve zamrezovane okna. Pozrite sa na mrezu na pravej strane. Pocet jej zvislych tyci je G.

Stage9 B-S-10 "Tri hranice"

Zo strechy objektu trci rura. Odmerajte jej priemer a zaokruhlite na desiatky cm. Priemer = H cm.

Stage10 B-S-13 "Stoh"

Na vonkajsej pravej bocnej stene je zamrezovana strielna. Mrezu v sucasnosti tvori I zvislych tyci. Kedysi to bolo este o jednu viac.

Stage11 B-S-14 "Duna"

Tento zrub ma J strielni. Netreba hladat nejake chytaky, vsetky su dobre zvonka viditelne.

Stage12 B-S-15 "Ostrov"

Vystverajte sa na strechu a spocitajte vsetky kovove oka na jej obrube. Ratajte iba tie, ktore su stale pripevnene ku stavbe. Vyjde vam cislo K (delitelne tromi).

EN:

In the years 1935 to 1938, Czechoslovakia was building a massive fortification of its borders. Thousands of forts were built against the threats from Nazi Germany, but also from other neighboring states. It was planned to build the whole line of border fortification until 1951, with the exception of 200 km border segment with Romania. Moreover, the strategic inland lines should have been fortified, too. The construction was canceled in september 1938, as a result of the Munich Treaty.

The munition was inspired by the French Maginot line. It consisted of light and heavy objects. The heavy fortification mainly consisted of a line of infantry blockhouses. Their embrasures were oriented along the line, so that the lines of fire of neigboring blockhouses were overlapping. From the enemy's side, the forts were smothered by soil. Anti-tank and anti-infantry obstacles were installed between neighboring objects.

The budget of the complete munition was planned to be 10.9 billion Czechoslovak crowns. Until the end of the construction, about 25% of this amount was actually spent. After the construction stopped, the half-built forts remained in different states of completion. The heavy fortification of the area on the right bank of river Danube was at that time complete. During the war, this area fell under dominion of Germany. However, the objects were not destroyed, as in many other places.

15 infantry blockhouses were built in the area of Petrzalka. Out of those, 12 survived till today. The other three were destroyed during the massive building of new Petrzalka - the suburb of Bratislava. In addition, there were 4 commander forts and several supporting objects. This multicache will take you to all of the 12 remaining infantry blockhouses of the battle line.

Don't forget to bring a distance meter. You will need it.

The stages of this cache are not about nice places. Actually, you may encounter a lot of trash at some of the objects. Moreover, homeless people or vandals may sometimes reside in the forts. So, please don't go caching at night, and if you feel unsafe while getting a particular clue, rather post me a message to get it.

If you are searching in a wet season, be prepared for tons of mud in your way. It's not recommended to go caching dressed in white linen trousers.

For those who are still not fed up with bunkers, there is a sequel available.

NATURE CONSERVATION: Stages 1, 2, 3, 4, 10, 12 and the final cache are located in nature-protected areas. Please don't try to drive up to these locations. Especially critical are the last stage and the final location, which are located in a nature reserve with 5th (highest) grade of protection.

Stage1 B-S-1 "Sterkoviste"

2m inside the blockhouse, there is a graffiti tank sprayed in red. The number of its visible wheels is A.

Stage2 B-S-2 "Mulda"

Climb to the roof and look at the right steel dome. Measure the diameter of the opening in its top. Diameter = B cm.

Stage3 B-S-3 "Paseka"

Measure the width of the embrasure next to the entrance. The width should be measured at the outermost point of the embrasure opening. Round the width to tens of cm. Width = C cm.

Stage4 B-S-4 "Lany"

This fort is currently undergoing renovation. Have a look at the covered huge anti-tank cannon embrasure on the left side of the object. Count all the bolts visible on the embrasure and right below it. You get D.

Stage5 B-S-6 "Vrba"

To get this clue, climb to the roof of the blockhouse. Have a look at the wall with the entrance opening. There are E iron hooks sticking out of the upper part of the wall. There were 2 more iron hooks, which are now broken off. This fort is currently under renovation, so temporarily E = 4.

Stage6 B-S-7 "Cviciste"

This stage is in the middle of a corn field. It is inaccessible for a long part of the year due to heavy mud or corn. So, it is up to you if you give it a visit.

Stage7 B-S-8 "Hrbitov"

This fort is being reconstructed by a party of enthusiasts. The activity has started in the spring 2009 under the lead of Mr. Kosirer. If someone is present at the site, you may enter the object and perhaps get a presentation. To get the clue, walk a bit along the road to the reconstructed war cemetery from World War I. Its main gate is decorated by short (10 cm) horizontal steel rods. Count them up, add one more (currently missing) to get a round number F.

Stage8 B-S-9 "Kittsee"

This object is also undergoing reconstruction. The small entrance room has two windows, blocked by steel grids. The grid on the right side has G vertical rods.

Stage9 B-S-10 "Tri hranice"

There is an iron pipe coming out of the object's roof. Measure its diameter and round it to tens of cm. Diameter = H cm.

Stage10 B-S-13 "Stoh"

The embrasure on the right side wall is covered by a grating. The grating consists of I vertical bars. Formerly, there was one more bar, which is now cut.

Stage11 B-S-14 "Duna"

The fort is equipped with J embrasures.

Stage12 B-S-15 "Ostrov"

Climb to the roof and count all the iron hooks along the rim. There are K of them (divisible by 3). Count only those that are still attached to the object.
