37

Some of thestaves had their originalupper beveling left,otherswereshortened andrecut.Allstaves had been cut offatthebottomandthesill

was replacedwithabrickwall.Theroof construction had also been changed.

38

39

Itcould also bedebated if this istheoldest stave churchstillstandingorachurchbuilt 1848withalotof reusedmedievaltimbers.Most

probableallthestaves are rearrangedmorethan once,they aresurely shortened (probably alot),theground- androof- constructions are from

1848.

Webelieve itismorecorrect tosay itisachurchfrom1848withreusedmedievalmaterial.

There wereamixof reused parts,originalandnewones.Interestingly someof theolder repairings had almost thesamepatinaastheassumed

originalparts.

40

Thenorthwest corner

original.Though itisnot

41

Totheleft,theinsideof thestaves that we believeare cut flat.How

thestaves looked originally ishardtotell.

Some strangecuttingmarksfromavery damaged axecan beseen in

deeper dens hereandthere.

42

Thetoolmarksaredonewiththesameaxeandatthesametime ontheoldstaves andtheinserted repair wood.Therefore itissafe toconclude

that thetoolmarksarenotoriginalbutdone later.

43

51

Originally thebelltower mighthave had some kindof skirt,similar totheone ithastoday orjustaprotection forthesills.There areseveral

mortices left open that reveal that partshave been removed.Thetower isstabilizedbyasystemoflatticebraces,opennotchlappedtothe

postsoutside.(OnbelltowersinDenmark andSwedenthebraces aregenerally ontheinside.)Itisinteresting tosee that theoriginalbelltower

hassharp canted corners ontheposts,compared totheyounger tower.This can becomparedwithwhat we knowfromtheScandinavian

towers.They had adifferentlogicandpreferred irregularities andsharp corners onthehewn timber instead of regular dimensionsandround

corners.Theolder braces havesapwood that hasrotted andfallenoff.Originally theymay havehad canted corners.

52

Thelatticebraceshasbeenconnectedtothepostswithopen notched laps.Tecurved ends onthelaps isacraft phenomena that we find

occasionally alloverEuropeoncampaniles andbelfrys dating from1250-1510.

SalisburyCathedralThemain reasonwas to examine thescaffolding inthespire.

9

In1990,33samplesweretaken,in2003-2004,32moresampleswere

takeninordertodendrochronologically datetheconstruction.

Contrary to established theories thescaffoldingwas around 50years

younger than thespire.Probably itwas erected to repair damagethat

occured in1362.10

Wevisited thespirebut itwas notpossible forus to climb up inthe

scaffoldingbecauseof security reasons.Wecould see that thescaffolding

hadmany reused timbers,something theresults of the

dendrochronological analysis confirm.

Thecentraltower was built inthefirstdecade of the

13thcentury.

94

95

There are lotsof graffitiand

scribings inthetower.

96

Thestool that thebells arehanging in,ismade of

reused beams,probably partsfromtheelder tall

belltower that once stood insidethestone tower.

97

There aredeep cuttings fortheswingingbells intheformerbellbeam (nowupsidedown).Markings forassembly,resembling runes,can beseen

hereandthere.Itwould bepossible tofigureouthowthestandingbelltower looked like,bymaking adeeper examinationanddrawings of allthe

parts.Making adigitalorascale model of itcould give abetter understanding.Wevisited similar belltowers inLiege,Belgium,in2016.

Theroof construction overthenave inWinchestercathedral has

been rebuilt several times andtherefore itisamixof allkindsof

Thewesternpartshould havebeen rebuilt after afire inthe17th

similar to what we see inSwedenfromthis time.

107

Oneof thebeams hasclear tool marksfromahewing axegoingforward.Thescratches ontheedge of theaxeandthedirection of thecuts

reveal that.

108

TheWinchestercathedral’s roof iscoveredwith3-4mmlead plates.Onone oldroof boardwefound anoldleadnail withapiece of lead still

underneath.These leadnails sometimes havesmall”dots”,underits head,tobetter grab thelead sheet,sothehole forthenail doesn’t growand

causeleakage when temperaturechanges andthesheet expands/shrinks.

109

Southof thecathedral inWinchesterthereareanoldcityport,andtwo

moreatWinchesterCollege.They are stillingood health andare

definitelyworth taking acloser lookat.

There isalot of work behind buildingdoorslikethese,withfine

precisionandadvanced carpentry.

110

Thelaststopof ourroadtripwas inthecontrysideatasmallchurchinNorthStoke.Then we droveup toGuildford

castle andenjoyed thesummerflowers inthepark.

Itwas afew lovely days driving around,but thecloser to Londonwe got,themore intense was thetraffic.Thepeak

was whenwe weretrying to reach Heathrowrental car deport..Neveragain!!

Good byeEnglandfornow.See you again soon.

Summary:

Withthis PMwe hopetoinspireothers togoout there andseek informationthat ishidden inthebuildings.

Itwould bevery interesting tocontinuetheinvestigations andmakeadeeper comparison,withdetailed examinations,drawings andscale

models or3Dmodels,of belltowers,free standing andinsidecathedral towers,across theborders innorthern Europe.

Wehavealready awakened this thought inSweden,Denmark andNorway.Perhaps other countries could beinvolved inacrossoverborder

project inthefuture.
